A bullet whined off the top of the rock pile, and then there was silence


Minutes ticked by. Then, faintly, Rick heard a sound that could only have been a horse whinnying.

Scotty stood upright and climbed to the very top of the mesa. Rick started to yell, then choked it back. Scotty must know what he was doing. He saw his pal walk leisurely out of sight. Rick stood up, watching. In a moment Scotty reappeared, climbing down the incline he had used to get to the top. In a moment the boys were face to face.

"He's gone," Scotty announced. "Had a horse staked out below the opposite side of the mesa. I saw him ride off. He was too far away for me to get a good look at him."

"Mighty strange," Rick said with a sigh of relief.

Scotty nodded. "Strange is right. You know what? He saw me standing there on the rim. He turned and looked at me, and he waved."

"Waved?" Rick asked.

"Yep. It was a real jaunty wave."

Rick shook his head in bewilderment. "My, that was friendly."

"I thought so," Scotty agreed. "Come on, boy. We've got to make tracks out of here. Time is running out."

Rick collected his shirt and jumped into the jeep. Scotty backed around and headed toward the base as fast as the road allowed. Not until they were down on relatively level ground did they try to converse.

"The rifleman must have read about David and Goliath," Rick said. "Why else would he run off?"

Scotty chuckled. "He was helpless. He was in deadly peril, as the storybooks say. Seriously, I think he was helpless."

Rick stared at his pal. Scotty could mean only one thing. "Then he had no intention of hitting us?"

"I doubt it. He was shooting at short range, and even a poor shot couldn't very well have missed as often as he did. Besides, I don't think you'd find many poor shots with rifles in this country."

"Then he must have been trying to scare us off," Rick said thoughtfully. "When you started heaving rocks at him, he knew we weren't scaring very much."

"Not much," Scotty said ruefully. "I don't know about you, but my innards turned to custard."

Rick grinned. He knew exactly what Scotty meant. "If things had happened a little more slowly, I'd have dropped dead from sheer fright. But I didn't have time. Anyway, when you started with your sling, he had a choice of shooting for keeps or getting out of there. So he got. Is that how you figure it?"

"Exactly right. What other explanation is there? Stones against rifle slugs isn't much of a contest. I only tried it because there wasn't anything else to do."

"We could have stayed under cover until Mac and Pancho arrived," Rick pointed out.

"Negative. All he had to do was shift position and he'd have had a clear shot at us."

That was true, Rick realized. "But why did he try to scare us off?"

"It beats me. He wasn't a guard, I'm sure. If he was guarding something, he wouldn't have ridden off and left us there. And there wasn't anything personal in it, because he waved at me like an old pal. It was a kind of humorous wave. You know? Real jaunty."

Rick asked the obvious question. "Was it the Earthman?"

And Scotty made the obvious answer. "I didn't have a chance to ask him. Anyway, he didn't wear armor."

Rick had been keeping his eye on the road ahead. "Pull over," he said quickly. "Let's get out and be looking at cactus or something. I think Mac and Pancho are coming."

Scotty complied quickly and shut off the jeep engine. The boys got out and walked quickly into the desert, found a barrel cactus, and began dissecting it with Rick's scout knife.

The dust cloud that marked an oncoming vehicle grew larger, and in a few minutes they saw the panel truck and the trailer with radar dish mounted on it. As the truck drew nearer they stood up, Rick holding the cactus impaled on his knife. It was a natural action; simple curiosity would require that they pause to see who might be in a passing vehicle.

The truck drew abreast and slowed. Big Mac was driving. Pancho leaned out and waved. "Hiya, kids!"

They echoed him. "Hiya, Pancho." Then the truck was past, en route to the mesa for the day's dry run.

Rick drew a deep breath. "In the clear," he said with relief. Suddenly he grinned. "This is what I call progress. We go to Careless Mesa. We find nothing. We get shot at. We add to the mystery without adding a single thing to the puzzle. One more day like this and we'll have to put our Junior G-man badges back in the cereal box where we got 'em."

"I beat you," Scotty said unhappily. "I left mine under a rock at the top of the mesa."


CHAPTER VIII

Project Orion

There was an air of anticipation everywhere at the Scarlet Lake rocket base. Rick, who was sensitive to such things, felt it keenly. He also recognized that under the anticipation, like thick, stagnant water under the bright surface of a pond, there was fear.

The anticipation was spoken; the fear was not.

By mutual agreement, Rick and Scotty parted soon after their return to the base. Each went back to his own unit, more on guard then ever before for the slightest hint of irregularity in personnel or equipment.

The electronics group of Pegasus was just about at a standstill. Dick Earle and Frank Miller had gone to the firing area, to lend the Orion group a hand. Dr. Bond remained, along with Kassick and Sherman. The three were amusing themselves with a game of three-handed bridge, while the marmoset occasionally made things lively by stealing cards.

Rick watched for a few minutes, then wandered into the empty Orion shed, abandoned now that its crew and rocket had moved to the firing pad and blockhouse. As he stood looking at the complex test equipment a sedan pulled up and Gee-Gee Gould got out. The electronics chief waved at him and trotted by into the project office. He returned in a moment with a portable tube and circuit tester under his arm and paused to ask, "What's up, boy-oh?"

Rick answered briefly, "No transistors, no work."

"Bored?"

"Not exactly, sir. But I wish I could do something useful instead of just hanging around."

Gee-Gee stroked his magnificent mustache. "I'm with you," he said finally. "Jump in."

Rick needed no further invitation. He took the tester from the scientist and climbed into the sedan, holding the gadget on his lap. "Where are we going?" he asked.

"Pad. Work to do, and you can help. Do a good job with me and I'll give you a special reward. Check?"

"Check," Rick agreed, grinning. "What's the reward?"

"Watch Orion from the blockhouse with me. Good?"

"Plenty good," Rick said, pleased. "What's the work?"

Gee-Gee drove the way he talked, at high speed and with a flourish. Rick held his breath as the sedan skidded around a gasoline truck, then leveled off. Gee-Gee gave him a long glance and almost went off the road in consequence.

"You're fairly new, Rick. But you know about this Earthman?"

"I've heard plenty of rumors," Rick agreed, "but I can't say I know many facts about him. He's a big, noctilucent mystery to me." He thought, "Now he's got me doing it!"

"I like that," Gee-Gee said appreciatively. "High, rare, and mysterious. Like noctilucent clouds high above the cirrus belt. I can use it."

Rick chuckled. "You were talking about the Earthman," he prompted.

"Yes. You weren't here for the first two shoots, so you are not this Earthman. And I'm not. No one knows this but me, on account of everyone suspects everyone. So far, only the Earthman knows who he is. But I'm telling you, it's not me. You don't have to believe this, of course, but, young Brant, I'm going to check every electronic circuit in Orion myself. And you're not only going to help me, you're going to check what I check. Roger?"

"Roger," Rick replied grimly. "How long will it take?"

"All night. We'll live on sandwiches and coffee and get no sleep. But when we're through, we'll both be satisfied that all electronics in Orion are correct and functioning."

"But hasn't the rocket been checked already?" Rick asked.

"Twice. Every circuit in it. The critical circuits have been checked a dozen times. But is ole Gee-Gee satisfied? Negative, young Brant. Gee-Gee is not going to be satisfied until he personally rechecks and locks all access doors and ports himself."

Rick sat back in the seat, smiling to himself. He had no doubt that Dr. Gerald Gould meant every word of it. If Orion failed tomorrow, it would not be the fault of the electronics department.

The sedan pulled up at the pad and Rick got out, staring at the great rocket. Myriad cables dripped from various parts of it, and he thought of Gulliver tied down by the threads of the Lilliputians. There was something magnificent about the clean, towering shape that stirred his imagination. In the jargon of the rocketeer the great missiles were called "beasts" or "birds." The former was because they sometimes acted "beastly." The latter was a tribute to their beautiful flight when they ran true.

Rick thought, "How could anyone sabotage a thing like that?"

Gee-Gee brought him back to earth. "Ever climb a gantry?"

"No, sir."

"Well, start flying, young Brant. We go to the top and work down."

Rick went. He was too excited to be afraid. The first stage was by elevator. Then he and Gee-Gee climbed thin steel rungs to the very tip of the great rocket. Not until he reached the shaky, wind-blown, postage-stamp-size platform at the top did he take time to look down.

The thin steel web was no barrier to vision. He was on top of the world, at the doorstep to space, looking down on fantastic activity below. The rocket curved sweetly away below him, down to the sharp lines of the great stabilizer fins. He noted the breakaway zone where the first stage and second stage were joined. He could see, as one perched on a cloud, the tiny, busy forms of men below.

For an instant, as the nose access port yawned before him, Rick had a vision of himself in pressure suit and plastic helmet, mounting the rocket as a pilot mans his plane, anticipating the signal for blast-off.

Gee-Gee brought him back to earth with a prosaic, "Let's get at it, boy-oh."

It was the beginning. The picturesque but highly competent and efficient electronics chief hadn't exaggerated. The fabulous world of rocketry narrowed to a maze of wiring, circuit after circuit, checking, testing, and calling for test signals from the blockhouse. Rick checked and rechecked, following closely on Gee-Gee's heels. He missed nothing, took nothing for granted. Once he snapped, "Wait a minute! You didn't check that circuit properly. Check for polarization as well as contact."

Gee-Gee looked at him in astonishment, then slowly grinned. He thrust out a grimy hand. "You're my boy, young Brant. Who taught you about polarization?"

Rick was about to say, truthfully, "My father." But he caught himself in time. "A boss I had at Spindrift."

"He taught you well, and you're right. I did goof on that one. I'll check, and you recheck."

They went at it again, inch by inch through the incredible maze of wiring in the rocket's innards. By very accurate analogy, they were probing the rocket's brains. The circuits, like nerves, carried messages to and from the central rocket control. One would signal "Rocket starting to yaw," and another would reply to the servomotors that activated the gimbal-mounted motor, "Compensate! Two degrees correction azimuth 350!" and the great rocket would steady on course again. There was a circuit to carry the heartbeats of the monkey caged in the nose cone, and another to carry his skin temperature, and dozens more.

Rick didn't even notice when it grew dark. Sometime during the night someone thrust ham sandwiches and a cup of steaming coffee into his hands and he ate and drank without taking his eyes from Gee-Gee.

Then, what seemed only minutes later, someone yelled, "Zero minus three hours!"

Gee-Gee looked up. He glared at Rick from red-rimmed eyes. "Quick! What's left to check?"

Rick stared at smudged, much-handled circuit diagrams through eyes that refused to focus sharply. "Only the control circuit for the pumps."

They were low on the crane now, working at the last access port. These were the electronic nerves of the great pumps that would force fuel into the rocket motor. Gee-Gee checked them, spoke into a walkie-talkie he had carried through the night, and Dick Earle's voice came back from the blockhouse. "The board is green."

Rick took over and checked again. And once more Earle's voice sounded, harsh and definite. "The board is green."

Gee-Gee slammed the access port door and locked the patented fasteners with a few turns of his screw driver. "We're done," he said flatly. "Come on down."

Rick followed, jumping to the ground from the lowest platform. He looked around, dazed. The sky was pink in the east. It was dawn. Where had the night gone? He stared amazed at grotesque figures that waited, silent, patient, like beings from another world. Then he realized it was the fueling crew dressed in protective clothing, swathed like strange cocoons in plastic that would keep their vulnerable human skins from the harm of corrosive liquid and fumes.

Gee-Gee led him to the blockhouse, and the walk across the barren plain cleared the mists from Rick's head. He knew, as clearly and finally as anyone can ever know anything, that the electronic circuits were all in order and functioning.

The massive door of the blockhouse was open. Inside were two dozen men, each with his own place and his own job. Rick knew some of them by sight, but he knew few names. This was the Orion crew. He looked at them with respect. They had made the great rocket on which he had worked all night. They had created it from sketches on paper, followed it through all the stages of construction until now it was ready.

A loud-speaker crackled, then boomed, "The time is now zero minus ninety minutes."

They were the fastest ninety minutes Rick had ever spent. He was enthralled by the activity in the blockhouse, and, careful to keep out of the way, he walked from station to station. Now and then he looked through the thick glass ports, and he saw the green mist of boron hydride as fuel throbbed slowly into the rocket's tanks.

A thin, bald scientist in a scarlet sports shirt picked up a microphone and spoke into it. "Tracking stations, report your readiness. Stand by. Lathrop Wells, report."

A loud-speaker over his head replied instantly. "Lathrop Wells ready and tracking."

Tonopah, Indian Springs, Mercury, Death Valley Junction, Shorty's Well, Chloride Cliff, Jubilee Pass: All ready and tracking. Then:

"Careless Mesa."

Big Mac's voice boomed forth. "Careless Mesa ready and tracking."

The time: "Zero minus thirty minutes!"

One by one red lights on the main board winked out and green lights came on in their places, showing circuits and controls in operation. Only a few red lights remained now. Rick looked through the glass ports and saw the gantry crane being wheeled away. Jeeps, trucks, and private cars were moving out of the area, haste evident in their spinning wheels and hunched drivers. The movement was like a scurry of ants. Rick watched, taking in everything. He didn't even notice when the massive door was swung shut, closing against its airtight cushion with a sibilant hiss.

"Zero minus five minutes."

At last the frenzied activity ceased, and the rocket stood alone, clean, beautiful, and awesome, only the instrument cable tying it to earth.

Rick couldn't tear his eyes from the rocket, even to watch the last of the red lights flick out, the green glow showing readiness.

Then, zero minus five ... four ... three ... two ... one ...

FIRE!

A steady hand threw the final switch.

Green flame stabbed from Orion's tail, grew to white intensity. The instrument cable dropped from the rocket's nose and writhed to the ground. Even through the thick walls of the blockhouse Rick heard the mighty rocket's voice, an ear-shattering roar of triumph that sent lancing pain through his head. The rocket shuddered, eager to be away. Thrust built up, and up, and up, and the exhaust light grew until it was like staring into the heart of a green sun. Then the great voice faltered, the shuddering increased.

A yell of pure horror burst from Rick's throat. High on the rocket's side, metal slowly peeled back like obscene steel lips opening, and green fire gushed forth. The shuddering ceased, and he knew the rocket was dead. The gash opened wider ... wider ...

The blockhouse door swung open and men poured out—silent, horrified men, helpless to do anything but watch, oblivious to the danger. Rick went out with them.

The desert was alive with sound now, with the roaring torch of rocket propellant and the scream of sirens. Speeding down from the base camp came the fire engines, to save what could be saved, to help still the flames so the Orion crew might find out what had gone wrong.

Behind the fire engines were jeeps, trucks, and cars, loaded with grim men who carried picks, shovels, anything to help still the holocaust.

Scotty arrived right behind the fire engines and ran to where Rick stood, still stunned by the shocking turn of events.

"What happened to it?" Scotty asked hoarsely.

Rick shook his head. He couldn't talk.

The firemen were already at work. Crews from the trucks, protected by asbestos and plastic, carried hoses to the very edge of the roaring propellant and began to smother it with mounds of foam. The men who had followed with shovels and picks were also at work, hastily digging a trench to prevent the spread of the fiery liquid.

Someone yelled, then another yelled. Rick looked up in time to see the rocket split wide open and most of the remaining tons of propellant gush out. The firemen saw it, too, saw that they would be engulfed. They turned and ran.

Horrified, Rick saw a fireman, clumsy in his protective suit, trip and fall before the oncoming flood of flaming boron hydride.

Scotty moved, instinctively, his finely trained body responding with perfect co-ordination. Straight toward the oncoming flood he ran, into the edge of the flames, leaping the rapidly widening trench. Rick ran, too, but Scotty's fast reaction had carried his pal beyond reach. He saw the husky ex-marine stoop into the flames, pick up the fallen fireman, and literally throw him across the trench to safety.

Then Rick was at his friend's side, slapping at the burning places on his clothes, rushing him away from the spreading propellant. But Scotty wasn't through. He helped the fireman to his feet and pulled at the protective suit. Rick saw instantly what had happened. The suit had been torn in the fall, and some propellant had gotten in through the rents. The fireman was burning under the protective cover!

Other hands came to help and they got the man out of his cover, out of his burning clothes. Then the first-aid squad moved in.

Not until the fireman had been cared for did Scotty say, almost apologetically, "Any of that stuff left? I've got a couple of burns."

Then Rick noticed for the first time that his own hands were scorched and in need of the soothing unguent. By the time he and Scotty were smeared with the ointment, the fire was out.

The boys watched as water was sprayed over the white-hot wreckage until at last the safety officer pronounced the torn remnants cool enough for inspection. Then John Gordon and the senior staff moved in.

It was past noon before they emerged from their inch-by-inch examination of the rocket, but no one left to eat, to change clothes, or even to sit down. No one thought of it.

John Gordon motioned to Dr. Albert Hiller, the Orion project officer. Hiller nodded. He spoke quietly, but not one of the hundreds watching missed a single word.

"Apparently a fuel-pump bearing froze at the critical moment. With an unstable fuel like boron hydride, that made the difference. Internal pressure was too much for the shell to take."

The engineer paused, and the tense, waiting silence became almost too much to bear. Hiller knew what the men were waiting for.

"We found no pictures," he said. "We'll continue the examination in the laboratory, of course. But as of this moment we cannot say whether it was the kind of accident that rocketeers always have to expect, or whether someone tampered with the pump. By someone, I mean—the Earthman."


CHAPTER IX

Ghost Town Clue

Rick refused point-blank to go to bed. He wasn't tired, he insisted, and he meant it.

Scotty yielded. "Okay. I see your point. It's hard enough to sleep in the daytime anyway, but when you're all keyed up, it's impossible. Didn't lunch make you sleepy at all?"

"A little, but that shower and change of clothes woke me up again. Scotty, I'll never forget that horrible instant when I realized that Orion wasn't going to take off. Honest, it was like watching something beautiful die. It..."

Hank Leeming, their security officer roommate, came into the bunkroom in time to hear Rick's last comment. Hank was young, usually smiling. He wasn't smiling now. "I was in the blockhouse when the first one blew. I know how you feel, Rick. It makes you want to lay violent hands on the man responsible."

The security officer changed the subject abruptly. "Luis Hermosa wants to see the boy who saved his life, and the one who helped."

"You mean the fireman who fell in the propellant?" Scotty asked.

"That's the one. He's in the infirmary. Can you both go?"

Scotty shrugged. "Sure. If he wants us to. But he doesn't owe us anything. Someone else would have dragged him out if we hadn't."

"If you hadn't," Rick corrected. "I didn't move fast enough."

"Neither did anyone else," Hank pointed out. "Don't be overmodest about it, Scotty. Go and see him."

The infirmary, operated by Lomac, was only a block away. Rick and Scotty walked over and checked in at the reception desk.

The infirmary clerk directed them to one of the four rooms in the little base hospital. "Go right in."

Luis Hermosa was awake. Rick knew he must be in pain from his burns, which were extensive, but his smile gave no evidence of it. It was a warm smile that demanded a smile in return.

"This morning there was no chance to give you my thanks," he greeted them. "I asked for you to come so that you may know how I feel."

Scotty put a hand gently on one of the bandaged ones. "No thanks are necessary."

Luis shook his head. "It was a brave thing. You might also have been caught by the fuel, and you did not even have a suit such as I wore. When I and my family light candles to thank God and to ask His blessing for you, we will want to give Him your names."

They told him their names, and his lips moved as he repeated them. Then he waved them to chairs. "Please sit down and talk with me for a few minutes. This is not a place where one can extend the hospitality of his house, but I can at least offer you chairs."

Keen brown eyes surveyed them. "You are both very young, eh? What are you doing here?"

"Working," Scotty answered. "I'm in vehicle maintenance and Rick is in Pegasus electronics."

"So? It is an exciting place in which to work. Even I, a fireman, feel this excitement. Tell me, do you think this hombre de terra, this Earthman, was the cause of the tragedy this morning? I call it a tragedy, because it was so. So much work, so much love went into that rocket! Sangre de Cristo! It was a terrible thing."

"No one seems to know for sure," Rick replied. "The project officer couldn't say. But there was no Earthman picture."

The bandaged hands spread expressively. "A picture could have been burned. Now perhaps we will never know. You understand, I have thought much about this thing. Once I believed this Earthman made the rockets go bad because he must think such things are against the will of God. But when I heard of the thefts, I no longer thought so. I thought about how a thief could take his stolen wealth from this guarded place."

"We've wondered about that, too," Scotty said.

"You decided something?"

Rick leaned forward on his chair. Luis Hermosa had started him thinking again.

"The thief couldn't get his stolen goods from the base if he went through a gate in his own car, could he?"

"He would not dare," Luis replied, "because he knows the guards check the trunks of cars, and sometimes even look under seats. He might be unlucky. He would know this."

"Spot check," Scotty nodded.

Rick hadn't known about the spot check, but it made sense. He continued, "So there's only one way. The thief has to take the stolen supplies from the base in an official vehicle."

"Such vehicles are not checked," Luis agreed excitedly. "But also, such vehicles are not taken far from this camp. If a truck, say, were gone too long, would it not be noticed?"

"It certainly would," Scotty stated.

"There must be only a few places where the thief could go," Rick said thoughtfully. "When he reaches one, he must hide his stolen goods and leave them. Later, by traveling a long way to reach the spot from the main road, he could get the stolen stuff with his own car. Or, maybe someone from outside who doesn't work on the base at all could go to the hiding place and pick them up. Can you think of any other way?"

Luis and Scotty couldn't, and said so.

Rick asked, "What are the possible places?"

"What would such a place need to be like?" Luis asked, then answered his own question, "It would need to be on a road, not only leading from the base, but to the outside. Also, it would need to be a lonely place, would it not? And it would need to be a place where the things could be hidden and not be seen, but where a helper from outside could find them easily. You see, I follow your reasoning. Where is such a place?"

The boys waited. Luis knew the area. He might have a good idea.

"There is one which is perfect. It is called Steamboat."

"But that's a town," Rick objected. "People would notice a truck from the base."

Luis chuckled. "People, yes. Ghosts, no. An evil man like this Earthman would not care what a ghost saw, would he? Ah, but you are new here, and you do not know. Steamboat is a town without people. No one has lived there for forty years."

"A ghost town," Scotty said in surprise. "But don't tourists go to ghost towns?"

"They do," Luis agreed. "They go to Searchlight, and to Rhyolite, and to Calico, and other ghost towns near here. But they do not go to Steamboat. It is on bad roads, many miles from the nearest good highway. Besides, who has heard of Steamboat? No newspaper writes about it, and no one advertises it. You cannot even buy a souvenir at Steamboat. There is no one to sell them. Ghosts do not peddle souvenirs."

Luis chuckled at his own joke. "You have a good head, Mr. Brant. I will think about this. Perhaps you will think some more, too, and we will compare notes later. Will you come to visit me again?"

"We'll come," they promised.

Outside in the brilliant sunlight, Rick said to Scotty, "You bet we'll go to see him again! How did you like his idea about the ghost town?"

"It can be reached from Careless Mesa," Scotty pointed out. "I wish we'd known it was a ghost town. We could have explored it some afternoon."

Rick said what had been on his mind since Luis made his suggestion. "I think we'd better pay it a visit."

"When?"

"What's the matter with right now?"

"Nothing, I guess. But why the rush?"

Rick wasn't sure himself. "Maybe there isn't any rush. But on the other hand, maybe there is. Look, we've kind of assumed Mac and Pancho are in on this, haven't we? Well, their movements must be pretty well known, at least while they're at work."

"They have to check their truck in and out. Why?"

"Let's talk about it over a coke. It's hot."

They hiked to the recreation hall and got cokes from the automatic dispenser. Rick set his thoughts in order.

"I'm not so sure about Mac and Pancho. They were at Careless Mesa this morning. At least I'm certain Mac was, because I heard his voice when he checked in by radio. And probably Pancho was, too, because it takes two men to handle a radar unit. One of them might have been able to sabotage a rocket, although I doubt it, but how could they take advantage of the confusion to steal the transistors when they're not even on the base?"

Scotty finished his coke and banged the bottle on the table for emphasis. "Okay. They couldn't. But why are you so sure they couldn't sabotage a rocket?"

"I'm not sure," Rick replied. "But now that I've seen how the base works, it seems to me that only someone who works on the rockets could sabotage one."

"Careful," Scotty said with a groan. "You're dumping the only suspects we have."

Rick grinned ruefully. "I know it. Anyway, we have to keep moving, even if it means starting all over again. So let's start at Steamboat."

"Okay. And just for the fun of it, I'll check the vehicle board. It won't hurt to know how much time Mac and Pancho have spent off the base in their truck. Suppose I gas up the jeep and meet you at the barracks?"

"I'll check out with Pegasus. Will you have any trouble?"

"No. Everything just about closes down the day of a shoot. I'll be there in ten minutes."

The boys parted at the door of the recreation hall and Rick started back to the barracks. As he passed the main administrative building, John Gordon fell in step.

"If I knew you two, I'd be mighty proud of both of you," the scientist said whimsically. "You for the job you did with Gee-Gee last night, and Scotty for pulling that fireman out this morning."

Rick smiled his thanks. "Anything new?"

"Not so far. Tom Preston is having the warehouses checked, just in case. But it's a terrific job going through an inventory item by item."

"Can you find out if the clerks leave the warehouses during a shoot?" Rick asked.

"Tom has already gone to work on that. I'll find a way to let you know. Keep in touch, Rick."

Rick continued on to the barracks, mind churning with confused thoughts. If only they had a few hard facts to work on! There wasn't a single definite clue to anyone. And, after last night, how could he suspect any of the dedicated, hard-working rocketeers? Impossible to imagine that anyone who had worked so hard on one of the projects could deliberately sabotage it. Yet, there was no other answer. No one outside the technical and scientific staff would have the opportunity or knowledge.

"At least," he concluded ruefully, "if we assume it's someone with ready access to the projects, we've cut down the size of the haystack. We're looking for one man out of only about five hundred!"


CHAPTER X

Stranded in Steamboat

The road to Steamboat led by Careless Mesa, then through a series of twists and turns down to comparatively level country again. According to the map, the ghost town was in a valley next to a dry lake bed.

Rick glanced at his watch. "It's going to be late when we get there."

"Maybe that's good," Scotty returned. "If anyone is in the town we'll see lights. This country is so wide open it would be hard to sneak up on the town in daylight."

"It would, if there was anything to sneak up for. Haven't you got the feeling this is a wild-goose chase?"

Scotty dodged a deep hole in the road. "It could be. But we can't just sit around waiting for the Earthman to hand us a calling card. Besides, Mac and Pancho were gone long enough to reach Steamboat and return to base this morning." That was what the vehicle-control board had shown.

"They might have been just waiting at Careless Mesa," Rick pointed out. "We have no evidence they went to Steamboat. Besides, if anything was stolen during the shoot this morning, they couldn't have been in on it."

"That's true. But we can't lose by looking the town over. Besides, I've never seen a real ghost town."

Rick watched the desert go by, his mind busy with the problems. As Scotty had said, if Mac and Pancho weren't in on the thefts, someone was. That someone had to get the stolen goods off the base and to a location from which it could be carried to civilization. He toyed with the idea that the stolen transistors might simply have been destroyed or hidden by the Earthman in order to hold up work at the base. That didn't seem likely.

The facts of time and distance certainly eliminated Mac and Pancho. During the shoots they were miles away. They had little or no opportunity to get close to the rockets. It was only reasonable to cross them—and all other radar-tracking teams—off the suspect list. Yet, Rick couldn't forget his initial feeling about the pair.

Scotty pointed. "Isn't that a town?"

The jeep had topped a gentle rise. Below lay a small, dry lake bed. At one edge of the dry lake, nestled in low foothills, were gray, weathered buildings. It was almost certainly Steamboat.

Scotty stopped the jeep and they surveyed the countryside with care. There was no sign of movement, no sign of a dust cloud from any other vehicle.

The sun was low in the west. In a short time it would be out of sight beyond the mountains, then darkness would close in. Rick reached into the jeep's glove compartment and found the flashlight he had stowed there. He checked it, then asked, "What are we waiting for?"

"Ideas," Scotty replied. "What say we roll right on through the town without stopping, then turn and come back through that wash at the base of the hills?"

Rick looked to where the dark-haired boy pointed. He saw the shadow of a gully that followed the foothills closely.

"Think it's necessary?" he asked.

Scotty shrugged. "Probably not. But it's better to be careful than sorry later."

"Okay with me. Let's go."

Scotty put the jeep in gear and they rolled swiftly down to the level of the dry lake bed and toward Steamboat. A few minutes later they entered the town.

Rick inspected the buildings with care. It looked like the setting for a Western motion picture, except for the lack of people and horses, and the lack of paint. He identified a pair of stores, a two-story building that could only have been a hotel, a livery stable, and several buildings without identification of any kind. There was only one street, and they were on it. Nowhere was there a sign of life. Then they were through the town, and the road climbed gently toward the foothills.

Scotty held the jeep at a steady speed for over a mile. As the road gradually curved around a rock outcropping, he said, "Look behind and tell me when the town is out of sight."

Rick turned in his seat in time to see Steamboat vanish behind the outcropping. "Now."

Scotty brought the jeep to a halt. "The road should fork pretty soon, shouldn't it?"

"That's right. Left fork to Pahrump Valley, right fork to Death Valley."

"Let's hit the ditch." Scotty reached down and put the jeep into four-wheel drive, then turned left off the road.

The bottom of the dry wash was alternately sandy and studded with boulders. Scotty picked his way with care, but it was a rough ride. Once or twice he stopped while Rick climbed the slope of the wash for a survey of the situation. Finally they pulled to a halt and both boys reconnoitered ahead, to find a good way out of the wash and onto the road. Satisfied that getting from the wash onto level ground would pose no problems, they turned off the jeep engine and settled down to wait.

Again, Rick felt the futility of what they were doing. They might wait for weeks without ever seeing another human being.

"There's going to be a moon," Scotty remarked.

Rick looked up at the slim crescent. "Yes, but not much of a moon. I'd rather depend on a flashlight."

Scotty stirred restlessly. "Maybe we should have explored the town."

"Maybe. It's too late now, except to explore by flashlight. We can always come back during daylight."

They fell silent while darkness settled in. Rick began to feel drowsy now that the excitement was at an end. He let his head droop. Presently he slept.

Suddenly he realized Scotty was shaking him. "I'm awake," he whispered. "What's up? What time is it?"

"Nearly nine. I was going to let you sleep for a while before starting back." Scotty's voice was low. "A car came along the road. Not from the base. The other way. It was traveling without lights. It stopped in town."

"Let's go," Rick whispered. He got out of the jeep, Scotty on his heels. They moved carefully up the slope of the wash and emerged on the open desert behind the town.

Scotty took his arm. "Follow me." The dark-haired boy moved into the lead.

They moved in a bent-over position, making their way from bush to bush, careful to move silently. Rick's pulse began to hammer. Why should anyone come to the ghost town, especially in a darkened vehicle? For the first time he felt hope. They might find out something of importance after all!

Scotty led the way, taking advantage of every bit of cover, and in a short time they emerged from the desert behind the row of ghostly, abandoned buildings. Rick recognized the hotel, the only two-story structure in the town. It was directly in front of them.

"Wait here a minute," Scotty whispered. He moved quickly and silently into the shadow of the livery stable. Scotty was skillful at this kind of work, and Rick knew it was best to let him reconnoiter alone.

Presently Scotty materialized from the shadows and moved to Rick's side. He whispered, "They came in a sedan. I couldn't see any lights, but I heard voices. They're in the hotel."

"Let's get closer," Rick replied softly.

Scotty plucked at his sleeve and Rick followed, moving swiftly into the shadow of the livery stable. Scotty moved slowly along the wall, then crossed the narrow alley between the stable and hotel with one long step, hesitating at the hotel corner. Rick followed silently. There was a window. Scotty crouched, so he would be below the window, and scuttled past it. Rick was right behind him.

The rear door of the hotel was next. Scotty's gesture told Rick they would stop there and try to listen. Scotty moved a few steps and stopped once more. He was in position. Rick crowded close behind him, then moved out from the wall a little so that he, too, could hear directly through the door.

From almost under his foot came a strident, warning buzz, and an icy ripple moved down his back. A snake! And he couldn't even see it! He froze where he was, muscles tense for the shock of needle-sharp fangs. He waited an eternity, not even daring to breathe. There were voices from within the hotel, but he didn't hear what they were saying. At that moment he couldn't possibly have cared less.

Then, his probing eyes saw the faint outline of the creature, half coiled, flattened head weaving. It was barely beyond striking distance. He watched it, not daring to look away, not daring to move.

Had Scotty heard the snake? But of course he must have. Rick reached with infinite caution and tugged at his pal's sleeve. Scotty would have to move first. Then Rick could move slowly to a position tight against the wall, where Scotty was now. Only by moving into the wall could he get away from the snake.

But in that moment the rattler apparently decided it had waited long enough. The evil head moved slowly toward Rick's foot.

Rick couldn't help it. He let out an involuntary yelp and jumped sideways, into Scotty. Scotty had no place to go but through the hotel door. He crashed into the rickety, partly hanging door, Rick on top of him.

Rick tried to get to his feet, sensing sudden noise and movement within the hotel, but he wasn't fast enough. A hand grabbed him by the arm and hauled him upright, and a fist glanced off his cheek-bone, snapping his head back.

Scotty, underneath, gathered his feet under him and charged like a plunging fullback, directly into the hotel. There was a grunt as the boy's head met yielding flesh, then a powerful arm circled his neck and he was lifted off his feet, fighting for breath.

A hand yanked Rick forward. His arms were twisted behind him. A pencil flashlight flicked on briefly and a voice muttered, "It's a couple of kids!"

Rick struggled, but subsided when it became clear that he could do nothing but wrench his arms out of joint.

A man muttered, "Rope in the car trunk."

Feet sounded on the boards of the hotel. Rick tried to pierce the gloom, to see his captors, but there wasn't enough light to see more than vague shapes. He had never heard the voices before. The feet came back. The voice said, "Lash 'em tight."

Rick was dumped face down on the dusty floor. Expert hands tied his wrists and ankles tight and lashed them together, with his knees bent at an acute angle and his shoulders pulled back. Next to him he sensed that Scotty was getting the same treatment.

A voice whispered, "Wonder who they are?"

"Doesn't matter," the first voice said. "We'll be out of here in fifteen minutes, if the others keep to schedule, and we won't be back. We can't use this place again."

A third voice broke in. "I didn't see a car. They must have cached it somewhere."

"You're right," the first voice agreed. "Find it, and fix it. Where'll we put these kids?"

The second voice had a suggestion. "The old jail across the street. We can lash 'em to the bunks."

Rick felt himself lifted like a sack of grain. He swayed as the man lugged him through the front of the hotel, across the porch, and into the street. His captor rounded the car that was waiting there and Rick strained to turn his head, to try to see the license plate, but couldn't catch a glimpse of it.

A creaky door was swung open and he was carried into an inner room and dropped face down. It knocked the breath out of him for a moment. When he recovered, he was tightly lashed to a rusty iron frame. His groping fingers felt the frame and the rope, but the knots were beyond his reach.

A voice asked, "Will we turn 'em loose later? We don't want 'em to die in here."

"They won't. They can get loose, but it will take a while and we'll be long gone. Come on."

The door creaked again. Rick listened to the sound of footsteps across loose boards, then there was silence.

Scotty whispered, "What do we do now? Wait for the Lone Ranger and Tonto?"

Rick had to grin, in spite of their plight. "Looks like it," he agreed. There was something ridiculous about being bundled into an antique Western jail. "Anyway, we didn't get bitten by that blasted snake."

"That worried me plenty," Scotty agreed. "Can you move at all?"

Rick's fingers hadn't stopped exploring. "Not much. How about you?"

"There's a sharp end of wire under my hands. I'm going to see if I can loosen the knots. Keep working."

"Don't worry," Rick whispered fervently. "I will."

Silence fell, except for an occasional scrape as they struggled. Rick's arms began to hurt, and his neck felt as though it would never straighten again. Gradually he worked the rope end into reach and began to move it, hoping to loosen the knot. Then there was a soft exclamation of triumph from Scotty.

"Are you free?" Rick whispered quickly.

"No. But I pulled the rope between my wrists and ankles loose enough so I can move. Just a minute."

Scotty got to his knees, balancing precariously. "I'm going to try to slide my hands down the frame to yours."

Rick strained his neck trying to see if there were any obstacles in the way, but he could see nothing. Scotty grunted. "I think I'm hung up on a bolt that's sticking through the frame." There was silence for a few moments while the boy struggled. "Made it," he muttered. "The ropes loosened a little."

Presently Rick felt Scotty's fingers and moved his own, seeking the ropes around his pal's wrists. He probed, trying to find the key to the knots. Finally, his right forefinger touched a free end, and he followed it into a twist of rope. His first two fingers could just reach the twist, and he set to work on it, moving the rope back and forth, trying to pull on it. Suddenly it gave.

"One," he said softly. There was another knot immediately under the loop he had just untied. It was tougher than the first one, but eventually he made it.

"I think you loosened it a little," Scotty said. "Maybe I can slide a knot over that bolt and pull loose."

Scotty moved away from him, sliding his hands along the rusty frame. The boys worked in silence, Rick tackling his own knots again while Scotty tried to use the rusty bolt as a lever.

Rick had to give up for a while. His hands hurt too much, and he knew that Scotty's must be hurting, too.

"Listen!" Scotty said suddenly.

A car, or a truck, was approaching the town, from the direction of Careless Mesa!

The boys tackled the knots with desperation and suddenly Scotty fell forward as his hands loosened.

Outside, the car braked to a stop. Rick wondered if Mac and Pancho had come to keep a rendezvous? He couldn't get rid of the feeling that those two were involved somehow.

"A few minutes more," Scotty gritted. "The knots are loose." Then, "I got it."

Moving swiftly, Scotty untied his ankles and knelt at Rick's side. Long minutes later Rick felt the ropes fall from his wrists. It didn't take long to get his ankles free, and he stood up, rubbing circulation back into his hands.

Scotty went to the doorway of the old jail and Rick joined him. "See anything?"

"No," Scotty whispered. "We'll have to go outside."

"We can't go out the front," Rick murmured. "They'd see us. That car stopped right in front. Let's see if there's a back entrance of some kind."

He led the way to the rear of the jail building, walking carefully in the darkness. There were windows but they were barred. He carefully felt his way past the jail's only cell, and along the back wall.

Outside, a motor spun into life.

Rick whirled. "They're going!"

Another motor started.

The boys turned and hurried to the front of the building. They were in time to see a sedan shift and speed away from the hotel, following the road toward civilization.

They hurried into the street and Scotty pointed in the opposite direction. The road back to the base was a dim, pale ribbon in the faint moonlight. Along it a dark shape was speeding.

"That does it," Rick said aloud.

Scotty turned to watch the departing sedan. "It didn't take them long to complete their business, whatever it was. I didn't hear any talk, did you?"

"Not a word. Do you suppose that was Mac and Pancho that came from the base?"

"No way of knowing, but it could have been. Come on. Let's find our jeep."

The jeep was where they had left it, but the hood was up. Scotty hurried to look, while Rick went to the glove compartment. The flashlight hadn't been touched. He got it and joined Scotty, throwing the beam under the hood.

For a moment everything looked normal, then Rick saw that the distributor cap and rotor were missing. The question was, had the men simply hidden them? Or had they taken the parts along?

Scotty put his thoughts into words. "If the parts are here, we'll find them in the morning. If they aren't ..."

Rick finished, "We'll be here until someone finds us!"


CHAPTER XI

Deadrock Ogg, Mayor

At dawn's first light Rick and Scotty began the search for the distributor cap and rotor. The boys searched methodically, taking in the area far beyond throwing distance, on the assumption that whoever had taken the two essential parts might have walked a distance away from the jeep before throwing them as far as he could.

"It's not here," Rick said positively.

Now all that remained was the town itself. They walked back to the town, Rick carrying the water bag and Scotty the canteen. At least their water hadn't been dumped.

Scotty paid careful attention to the vehicle tracks in the dust of the road.

"It's pretty clear," he pointed out at last. "Here's where the sedan was parked. And here's where the other vehicle parked. See how this area is scuffed up? They made quite a few trips, carrying something from the side of the vehicle to the rear of the sedan, probably stowing the stuff in the luggage compartment. And, from the tire tracks, I'd say the vehicle from the base was a light truck."

"Like Mac's truck?" Rick asked.

"Maybe. Anyway, whoever it was had to go through the guard gate, and the run might even be chalked up on the board. Not to here, of course, but maybe to Careless Mesa or Dry Spring."

"We can check when we get back," Rick said. "Come on. We'd better take the town apart and see if the rotor and distributor cap are here."

It was midmorning before they gave up the search, and both of them were exhausted.

"Now what?" Rick asked wearily. He had never in his life felt so badly in need of sleep. Except for a few brief catnaps in the jeep, he had been awake continuously for forty-eight tense hours.

Scotty scratched his head. "There are a few buildings we haven't searched yet."

"No, but they wouldn't be in those. If the men were going to leave them here, they'd drop them nearby and not hide them in one of the distant buildings. But I suppose we'd better look, anyway."

"We'd better. I'm fresher than you are. Go stretch out in the hotel lobby and I'll look."

Rick was too tired to argue. He walked into the comparative coolness of the rickety old hotel and found a section of undamaged floor. He removed his shoes, stretched out, and was asleep almost at once. In a short time Scotty joined him after an unsuccessful search.

When Rick woke again it was dark and Scotty was stretched out beside him, sound asleep. He turned over and went to sleep again.

Both boys woke up, stiff and bleary-eyed, as dawn light flooded the hotel. They grinned at each other.

"I must have slept for two days," Rick said.

"Not quite. Just about sixteen hours. But you needed it, and there wasn't anything to do."

"We're okay so long as the water lasts, but then what?" Rick knew without even putting it into words that they could never walk to civilization. Their water would run out and heat exhaustion would get them before they were halfway to anywhere. The base was closest, and it was over thirty miles away, across desert and waterless mountains.

Scotty walked over to what had once been the hotel desk and held up a can. "Want some breakfast?"

Rick was at his side in an instant, examining a can of tomatoes. "Where did you get it?" It was shiny, the label unfaded.

"Down the street. In one of the houses. Someone comes here now and then, I guess. There are blankets, a sleeping bag, and a small supply of food."

Rick's brows knitted. "Shouldn't we have been standing guard?"

"I thought about it," Scotty admitted, "but I figured there wasn't much sense to it. We'd welcome friend or foe at this point. Anyway, I don't think whoever hangs out here is part of the gang."

"Why not?"

"Wouldn't the gang have been at his hide-out instead of here in the hotel? Besides, this looks like a cache for just one man."

Rick had to admit that made sense. "Do you suppose he's here now?"

"I doubt it. I'd have heard a car if one came into town last night. I wasn't sleeping that soundly."

"Well, I'm grateful to him, whoever he is. Let me at that can." Rick searched in his pocket and found his scout knife. He opened the can-opener blade and got to work. In a moment they were taking turns drinking the slightly acid, refreshing juice and pouring whole tomatoes into their mouths.

An amused voice spoke from the doorway. "Looks good."

Standing on the porch was a figure in worn but clean denims and miner's boots. His face was weathered from years in the desert sun. His hair was grizzled where it could be seen under an ancient and disreputable flat-topped, broad-brimmed hat. His eyes, under shaggy brows, were a clear, twinkling blue. The man held a rifle; the muzzle pointed unwaveringly at the boys.

"That your jeep in the wash?" he asked.

"That's ours," Scotty affirmed.

"Mislay a few parts?"

"You might say so," Rick agreed. "Who are you?"

"I'm the mayor of Steamboat."

The boys started. "The mayor?" Rick echoed.

"Yep. Likewise the sheriff. As mayor, I welcome you. As sheriff, I want your names and business."

The boys gave their names, then Scotty asked, "How did you get into town? I didn't hear a car."

"Good reason. I didn't drive. Now, what are you doing here?"
