He stared at her speechless, so taken was he with the immensity of the thing she had suggested. Fear, wonder, joy seemed to contend for the mastery.

"Why do you look at me so, Tristan?" she said at last. "What is it that daunts you?"

"But how is this thing possible?" he stammered, still in a state of bewilderment.

"What difficulty does it present?" she returned. "The Lord Basil himself has rendered very possible what I suggest. We may look on him to-morrow as our best friend—"

"But Tebaldo knows," he interposed.

"True! Deem you, he will dare to tell the world what he knows? He might be asked to tell how he came by his knowledge. And that might prove a difficult question to answer. Tell me, Tristan," she continued, "if he had succeeded in carrying me away, what deem you would have been said to-morrow in Rome when the coffin was found empty?"—

"They would naturally assume that your body had been stolen by some wizard or some daring doctor of anatomy."

"Ah! And if we were quietly to quit the church and be clear of Rome before morning—would not the same be said?"

He pondered a while, staggered by the immensity of the risk, when suddenly a memory flashed through his mind that left his limbs numb as if they had been paralyzed by a thunderbolt.

It was the night on which the terrible crime at the Lateran was to be committed. Even now it could not be far from the midnight hour. Did he dare, even for the consideration of the greatest happiness which the world and life had to give, to forego his duty towards the Church and the Senator of Rome?

Hellayne noted his hesitancy.

"Why do you waste precious moments, Tristan?" she queried. "Is it that you do not love me enough?"

A negative gesture came in response, and his eyes told her more than words could have expressed.

At last he spoke.

"If I hesitate," he said, trying to avoid the real issue, instead of stating it without circumlocution, "it is because I would not have you do now of what, hereafter, you might repent. I would not have you be misled by the impulse of a moment into an act whose consequences must endure while life endures."

"Is that the reasoning of love?" she said very quietly. "Is this cold argument, this weighing of issues consistent with the hot passion you professed so lately?"

"It is," he replied. "It is because I love you more than I love myself, that I would have you ponder, ere you adventure your life upon a broken raft such as mine. You are still the wife of another."

"No!" she replied, her eyes preternaturally brilliant in the intensity of her emotion. "Hellayne, the wife of Roger de Laval, is dead—as dead to him, as if she in reality were bedded in the coffin. Where is he? Where is the man who should have been where you are, Tristan? I venture to say his grief did not overburden him. He will find ready consolation in the arms of another for the wife who was to him but the plaything of his idle hours. He never loved me! He even threatened to shut me up within convent walls for the rest of my days if I did not return with him—his mistress,—his wife but in a name, a thing to submit to his loathsome kisses and caresses, while her soul is another's. He himself and death, which perchance he himself decreed, have severed bonds no persuasion would have tempted me to break. Tristan, I am yours—take me."

She held out her beautiful arms.

He was in mortal torment.

"Nevertheless, Hellayne, to-night of all nights it may not be—" he stammered. "Listen, dearest—"

"Enough!" she silenced him, as she rose. She swept towards him and, before he knew it, her hands were on his shoulders, her face upturned, her blue eyes holding his own, depriving him of will and resistance.

"Tristan," she said, and there was an intensity almost fierce in her tones, "moments are fleeting, and you stand there reasoning with me and bidding me weigh what already is weighed for all time. Will you wait until escape is rendered impossible, until we are discovered, before you will decide to save me and to grasp with both hands the happiness that is yours; this happiness that is not twice offered in a lifetime?"

She was so close to him that he could almost feel the beating of her heart. He was now as wax in her hands. Forgotten were all considerations of rank and station. They were just man and woman whose fates were linked together irrevocably. Under the sway of an impulse he could not resist, he kissed her upturned face, her lips, her eyes. Then he broke from her clasp and, bracing himself for the task to which they stood committed by that act, he said, the words tumbling from his lips:

"Hellayne, we know not who is abroad to-night. We know not what dangers are lurking in the shadows. Tebaldo and his men may even now be scouring the streets of Rome for a fugitive, and once in their power all the saints could not save us from our doom. I know not the object of this plot of which you were the victim, and even the Lord Roger may be but the dupe of another. I will take you to the convent of the Blessed Sisters of Santa Maria in Trastevere, that you may dwell there in safety until I have ascertained that all danger is past. You shall enter as my sister, trying to escape the attention of an unwelcome suitor. But the thing that chiefly exercises my mind now is how to make our escape unobserved."

Hellayne nodded dreamily.

"I have thought of it already."

"You have thought of it?" he replied. "And of what have you thought?"

For answer she stepped back a pace and drew the cowl of the monk's habit over her head until her features were lost in the shadows. Her meaning was clear to him at once. With a cry of relief he turned to the drawer whence he had taken the habit in which she was arrayed and, selecting another, he hastily donned it above the garments he wore.

No sooner was it done than he caught her by the arm.

There was no time to be lost. Moments were flying.

If he should be too late at the Lateran!

"Come!" he said in an urgent voice.

At the first step she stumbled. The habit was so long that it cumbered her feet. But that was a difficulty soon overcome. Without regarding the omen, he cut with his dagger a piece from the skirt, enough to leave her freedom of movement and, this accomplished, they set out.

They crossed the church swiftly and silently, then entered the porch, where he left her in order to peer out upon the street. All was quiet. Rome was wrapt in sleep. From the moon he gleaned it wanted less than an hour to midnight.

Drawing their cowls about their faces, they abandoned the main streets, Tristan conducting his charge through narrow alleys, deserted of the living. These lanes were dark and steep, the moonlight being unable to penetrate the chasms formed between the tall, ill-favored houses. They stumbled frequently, and in some places he carried her almost bodily, to avoid the filth of the quarter they were traversing.

The night was solemn and beautiful. Myriads of stars paved the deep vault of heaven. The moon, now in her zenith, hung like a silver lamp in the midst of them; a stream of quivering, rosy light, issuing from the north, traversed the sky like the tail of some stupendous comet, sending forth, ever and anon, corruscations like flaming meteors.

At last they reached the Transtiberine region and the convent of Santa Maria in Trastevere hove into sight. The range of habitations around were in a ruinous state and the whole aspect of the region was so dismal as to encourage but few ramblers to venture there after nightfall.

Passing through the ill-famed quarter of the Sclavonians, where, in after time, one of the blackest crimes in history was committed, Tristan and Hellayne at last arrived before the gates of the convent. They had spoken but little, dreading even the faintest echo of their footsteps might bring a pursuer on their track. Their summons for admission was, after a considerable wait, answered by the porter of the gate, who, upon seeing two monks, relinquished his station by the wicket and descended to inquire into their behest.

Hellayne shrank up to Tristan, as the latter stated their purpose and the old monk, unable to understand the jargon of his belated caller, withdrew, mumbling some equally unintelligible reply.

Hellayne's eyes were those of a frightened deer.

"What will he do, Tristan?" she whispered, "Oh, Tristan, do not leave me! I feel I shall never see you again, Tristan—my love—take me away—I am afraid—"

He held her close to him.

"There is nothing to fear, my Hellayne! To-morrow night I shall return and place you safely where we may see each other till I have absolved my duties to the Senator. Do not fear, sweetheart! Of all the abodes in Rome the sanctity of the convent is inviolate! But I hear steps approaching—some one is coming. Courage, dearest—remember how much is at stake!"

Another moment and they stood before the Abbess of Santa Maria in Trastevere.

Summoning all his presence of mind, Tristan told his tale and made his request. Danger lurking in the infatuation of a Roman noble was threatening his sister. She had fled from his innuendos and begged the convent's asylum for a brief space of time, when he, Tristan, would claim her. He explained Hellayne's attire, and the Abbess, raising the woman's head, looked long and earnestly into her face.

What she saw seemed to confirm of the truth of Tristan's speech, and she agreed readily to his request. Tristan kissed Hellayne on the brow, then, after a brief and affectionate farewell and the assurance that he would return on the following day, he left her in charge of the Blessed Sisters. With a sob she followed the Abbess and the gates shut behind them.

For a moment Tristan felt as if all the world about him was sinking into a dark bottomless pit.

Then, suppressing an outcry of anguish, his winged feet bore him across Rome towards the Basilica of St. John in Lateran.


CHAPTER XIV
THE PHANTOM OF THE LATERAN

It still lacked a few minutes of midnight when Tristan arrived at the Lateran. The guard had been set in all the chapels, as on the night when he had kept the watch before.

Without confiding his purpose to any one, he traversed the silent corridors until he came to the chapel where he was to watch all night.

The men-at-arms were posted outside the door. A lamp was burning in the corridor, and strict orders had been given that no person whatsoever was to pass into the chapel.

After assuring himself that all was secure, Tristan seated himself in a chair which stood in the centre of the chapel.

The place was dim and ghostly. A red lamp burnt before the Blessed Sacrament, and from the roof of the chapel hung another lamp of bronze. The light was turned low, but it threw a slight radiance upon portions of the mosaic of the floor.

Tristan unbuckled his sword and placed it ready to hand. The whole of the Basilica was hushed in sleep. There was a heaviness and oppression in the air, and no sound broke the stillness in the courts of the palace.

Memory flared up and down like the light of a lamp, as Tristan pondered over the changes and vicissitudes of his life, with all its miseries and heart-aches, as he thought of the future and of Hellayne. Danger encompassed them on every side. But there had been even greater terrors when he had plucked her from the very grip of Death, from the midst of her foes.

And then he began to pray, pray for Hellayne's happiness and safety, and his whispering voice sounded as if a dry leaf was being blown over the marble floor, and when it ceased the silence fell over him like a cloak, enveloping him in its heavy, stifling folds.

He had been on guard in the Lateran before, but the silence had never seemed so deep as it was now. His mind, heated and filled with the events of the past days, would not be tranquil. And yet there was a deadly fascination in this profound silence, in which it seemed his own mind and the riot of his thoughts were living and awake.

What, if even now some lurking danger were approaching through the thousand corridors and anterooms of the palace! For on this night the enemies of Christ were abroad, silently unfurling the sable banners of Hell.

The thought was almost unbearable. It was not fear which Tristan felt, rather a restlessness he was unable to control. Although the night was no hotter than usual, perspiration began to break out upon his face, and he felt athirst. The fumes of incense that permeated the chapel, increased his drowsiness.

With something of an effort Tristan strode to the door and opened it. In the corridor two men-at-arms were on guard, one standing against the wall, the other walking slowly to and fro. The men reported that all was well, and that no one had passed that way. Tristan closed the door and returned inside. He walked up the chapel's length and then, his drawn sword beside him on the marble, knelt in prayer before the Blessed Sacrament which he had come to guard.

There, for a little, his confused and restless mind found peace.

But not for long.

A drowsiness more heavy and insistent than any he had ever known began to assail him. It billowed into his brain, wave after wave. It assailed him with an irresistible, physical assault. He fought against it despairingly and hopelessly, knowing that he would be vanquished. Once, twice, sword in hand, as though the long blade could help him in the fight, he staggered up and down the chapel. Then, with a smothered groan, he sank into the chair, the sword slipping from his grasp. He felt as if deep waters were closing over him. There was a sound like dim and distant drums in his ears, a sensation of sinking, lower, ever lower,—then utter oblivion.

And now silence reigned, silence more intense than his mind had ever known.

The red lamp burned before the Host. The lamp in the centre of the chapel threw a dim radiance upon the bowed form of Tristan, whose sword crossed the mosaics of the floor.

Silence there was in the whole circuit of the Lateran.

Even the Blessed Father, prisoner in his own chamber, was asleep. The domestic prelates, the whole vast ecclesiastical court were wrapt in deep repose.

In the chapel of St. Luke the silence was broken by the deep breathing of Tristan. It was not the breathing of a man in healthy sleep. It was a long-drawn catching at the breath, then once more a difficult inhalation. The men-at-arms outside in the corridor heard nothing of it. The sound was confined to the interior alone.

The ceiling of the chapel was painted, and the various panels were divided by gilded oak beadings.

Almost in the centre, directly above where Tristan reposed in leaden slumber, was a panel some two feet square, which represented in faint and faded colors the martyrdom of St. Sebastian.

Suddenly, without a sound, the panel parted.

If the sleeper had been awake he would have seen almost at his feet a swaying ladder of silk rope, which for a moment or two hissed back and forth over the tesselated floor.

Now the dark square in the painted ceiling became faintly illumined. In its dim oblong a formless shape centred itself. The faint hiss from the end of the silken rope ladder recommenced and down the ladder from the roof of the chapel descended a formless spectre, with incredible swiftness, with incredible silence.

The spider had dropped from the centre of its web. It had chosen the time well. It was upon its business.

The trembling of the rope ladder ceased. Without a sound the black figure emerged into the pale light thrown by the central lamp. The figure was horrible. It was robed in deepest black, and as it made a quick bird-like movement of the head, the face, plucked as from some deadly nightmare, was so awful that it seemed well that Tristan was unconscious.

The High Priest of Satan stood in the chapel of the Lateran. His quick, dexterous fingers ran over Tristan's sleeping form. Then he nodded approvingly.

There was a soft pattering of steps and now the black form passed out of the circle of light and emerged into the red light of the lamp, which burned before the altar.

Above, upon the embroidered frontal, were the curtains of white silk edged with gold—the gates of the tabernacle.

A long, lean arm, hardly more than a bone, drew apart the curtains. Mingling with the heavy breathing of the sleeping man there was a sharp sound, most startling in the intense silence.

It was a bestial snarl of satisfaction. It was followed by abominable chirpings of triumph, cold, inhuman, but real.

Tristan slept on. The men-at-arms kept their faithful watch. In the whole of the Lateran Palace no one knew that the High Priest of Satan was prowling through the precincts and had seized upon his awful prey.

He thrust the Holy Host into a silver box, and placed it next to his bosom. Then he drew a wafer of the exact size and shape of the stolen Host from the pocket of his robe. Gliding over to Tristan he thrust this unconsecrated wafer into his doublet.

Then the black bat-like thing mounted to the ceiling. The lemon-colored light reappeared for a moment. In its glare the dark phantom looked terrific, like a fiend from Hell. The rope ladder moved silently upwards, and the painted panel with the arrow-pierced Sebastian dropped soundlessly into its place.

The red lamp burnt in front of the tabernacle. But the chapel was empty now.

At dawn the unexpected happened.

The guards, expecting to be relieved, found themselves face to face with a special commission, come to visit the Lateran. It consisted of the Cardinal-Archbishop of Ravenna, the Cardinal of Orvieto, the Prefect of the Camera and Basil the Grand Chamberlain.

After having made the rounds they at last arrived before the chapel of St. Luke. They found the two men-at-arms stationed at the door, alert at their post. The men were exhausted; their faces appeared grey and drawn in the morning light, but they reported that no one had passed into the chapel, nor had they seen anything of Tristan since midnight, when he had questioned them.

The doors of the chapel were locked. Tristan held the keys. Repeated knocks elicited no response.

The Archbishop of Ravenna looked anxiously at the Prefect of the Camera.

"I do not like this, Messer Salviati," he said in a low voice. "I fear there is something wrong here."

"Beat upon the door more loudly," the Prefect turned to one of the halberdiers, and the man struck the solid oak with the staff of his axe, till the whole corridor, filled with the ghostly advance light of dawn, rang and echoed with the noise.

The Prefect of the Camera turned to the Archbishop.

"It would seem the Capitano has fallen asleep. That is not a thing he ought to have done—but as the chapel seems inviolate we need hardly remain longer."

And he looked inquiringly at the Grand Chamberlain.

The latter shook his head dubiously.

"I fear the Capitano can hardly be asleep, since we have called him so loudly," he said, looking from the one to the other. "I would suggest that the door of the chapel be forced."

They were some time about it. The door was of massive oak, the lock well made and true. A man-at-arms had been despatched to another part of the Lateran to bring a locksmith who, for nearly half an hour, toiled at his task.

It was accomplished at last and the four entered the chapel.

It stretched before them, long, narrow, almost fantastic in the grey light of morning.

The painted ceiling above held no color now. The mosaics of the floor were dead and lifeless. In the centre of the chapel, with face unnaturally pale, sat Tristan, huddled up in the velvet chair. By his side lay his naked sword.

The lamp which was suspended from the centre of the ceiling had almost expired.

In front of the altar the wick, floating on the oil, in its bowl of red glass, gave almost the only note of color against the grey.

As they entered the chapel, the four genuflected to the altar. And while the Prefect and Basil went over to where Tristan was sleeping in his chair, and stood about with alarmed eyes, the Cardinal of Orvieto and the Archbishop of Ravenna approached the tabernacle with the proper reverences, parted the curtains and staggered back, indescribable horror in their faces.

The Holy Host had disappeared.

The priests stared at each other in terror. What did it mean? Again the Body of Our Lord had been taken from His resting-place. The captain of the guard was asleep in his chair. Verily the demons were at work once more and Hell was loosed again.

The Archbishop of Ravenna began to weep. He covered his face with his hands. As he knelt upon the altar steps, great tears trickled through his trembling fingers, while he sent up prayers to the Almighty that this sacrilege might be discovered and its perpetrators brought to justice. On either side of him knelt the priests who had come into the chapel after them. Their hearts were filled with fear and sorrow.

The Cardinal of Ravenna rose at last.

His old, lean face shone with holy anger and sorrow.

"An expiatory service will be held in this chapel before noon," he addressed those present. "I shall myself say Mass here. Meanwhile the whole of the palace must be aroused. Somewhere the emissaries of Satan have in their possession the Blessed Sacrament. See that the secret Judas does not escape us!"

Almost upon his words there came a loud wail of anguish from the centre of the chapel where Tristan was still huddled in his chair.

Basil had opened the doublet at his neck, as if to give him air, and the Prefect of the Camera, who was standing by, clapped his hands to his temples, and groaned like a soul in torment.

The two ecclesiastics hurried down from the altar steps.

Upon the lining of Tristan's doublet there lay the large round wafer, which every one present believed to be the consecrated Host.

The Cardinal-Archbishop reverently took the wafer from Tristan and held it up in two hands.

The men-at-arms sank to their knees with a rattle and ring of accoutrement.

Every one knelt.

Then in improvised procession, His Eminence restored the wafer to the tabernacle.

Tristan was dragged out of the chapel.

In the corridor horror-stricken men-at-arms buffeted him into some sort of consciousness. His bewildered ears caught the words: "To San Angelo," as he staggered between the men-at-arms as one in the thrall of an evil dream, leaving behind him a nameless fear and horror among the monks, priests and attendants at the Lateran.

END OF BOOK THE THIRD

BOOK THE FOURTH

CHAPTER I
THE RETURN OF THE MOOR

In a domed chamber of the Emperor's Tomb there sat two personages engaged in whispered conversation, Basil and a weird hooded phantom that seemed part of the dread shadows which crowded in upon the room, quenching the dying light of day. Deep silence reigned. Only the monotonous tread of the sentries broke the stillness as they made the rounds above them.

It was Basil who spoke.

"All is going well! We shall prevail! We shall set up the throne of Ebony in the stead of the Cross. I bow to your wisdom, my master! The promised reward shall not fail you!"

As he spoke, the thin, black arm of his vis-a-vis trembled for a moment in the ample folds of his black gown. Then, with a quick, bird-like movement, a thin hand, twisted like a claw, wrinkled and yellow, was stretched out towards the Grand Chamberlain.

On the second finger of this claw there was a ring. Basil bent and kissed it.

Basil began to speak in his ordinary, conversational tone, but there was a strange gleam in his eyes.

"It has been accomplished," he said. "They tell me all Rome is astir!"

The voice that replied seemed to come from a great distance; the lips of the waxen face hardly moved. They parted, that was all.

"It has been done! I took it myself! It was the Host which the Cardinal of Ravenna had consecrated on that morning."

"And you were not seen?"

"I was not," came the whispered reply. "As a measure of precaution I wore the mask which I use to go about the churches at night. I met no one."

"Is it here?" Basil queried eagerly.

"It is not here," replied the voice. "It must be kept until the night of the great consecration, when Lucifer himself shall sit upon the ebony throne and demand his bride—his stainless dove. Where is she now?"

The light had faded out of Basil's eyes, and his face was ashen.

"One has been found, worthy of even as fastidious a master as he, whom we both serve. Well-nigh had she escaped us, had not one who never fails me tracked her on that fatal night, when her body lay in her coffin ready to be consecrated to the Nameless one."

From the eyeless sockets of the shadow-mask a phosphorescent gleam shot towards the Grand Chamberlain.

"What of the man?"

"The wafer was discovered on a certain captain of the guard who hath crossed my path to his undoing once too often. The Church herself shall pronounce sentence upon him—through me!"

"And—that other?"

There was a pause.

"Her husband!—He deems her dead, nor grieves he overmuch, believing, as he does, that her love was another's—even his whom I have marked for certain doom. I have it in my mind to try what a jest will do for him."

The lurid tone of the speaker seemed to impress even his shadowy companion.

"A jest?"

"He shall attend the great ceremony," Basil explained. "And he shall behold the stainless dove. When is it to be?" he added after a pause.

"When is it to be?"

"Six nights hence—on the night of the full moon."

"And then you shall give to me that which I crave, and the forfeit shall be paid."

"The forfeit shall be paid," the voice re-echoed from the shadows, and to Basil it seemed as if the damp, cold breath from an open grave had been wafted to his cheeks.

Like a phantom that sinks back into the night of the grave, whence it had emerged, Bessarion vanished from the chamber. In his place stood Hormazd, who had noiselessly entered through a panel in the wall.

Basil greeted him with a silent nod.

"What of the messenger?" he turned to the Oriental.

"He returns within the hour," replied the voice.

"What are his tidings?" Basil queried eagerly. "Is Alberic in the land of shadows, where she dwells who gave him birth?"

"Sent by the same relentless hand across the Styx," the cowled figure spoke, yet Basil knew not whether it was a question or a statement.

He gave a start.

"Tell me, how are secrets known to you at which Hell itself would pale?" he turned with unsteady tone to his companion.

"Those of the shadows commune with the shadows," came the enigmatical reply. "Is everything prepared?"

"When the brazen tongue from the Capitol tolls the hour, the blow shall fall," Basil replied. "Hassan Abdullah and his Saracens are anchored off the port of Ostia. The Epirotes and Albanians in the Senator's service are bribed to our cause. Rome is in the throes of mortal terror. Even the Monk of Cluny is under the spell, and has ceased to arraign the Scarlet Woman of Babylon. The dread of the impending judgment day will succor our cause. And—once installed within these walls as master of Rome—with Theodora by my side—you shall have full sway, to do whatever your dark fancies may prompt. You shall have a chamber and a laboratory and be at liberty to roam at will through your devil's kitchen."

The cowled figure gave a silent nod, but, before he could speak, the door leading into the chamber opened as from the effect of a violent gust of wind, and a shapeless form, that seemed half human, half ape, flew at Basil's feet, who recoiled as if a ghost had arisen before him from the floor.

For a moment Basil stared from Daoud the Moor to his shadowy visitor, then he bade the runner arise and commanded him in some Eastern tongue to unburden himself.

With many protestations of his devotion the monster produced a bundle which Basil had not noted, owing to the swiftness with which the African had entered the chamber. Panting, with deft, though trembling fingers, Daoud untied the cords and a bloody head, severed from its trunk, rolled upon the floor of the chamber, and lay still at Basil's feet. It had lost all human semblance and exhaled the putrid odor of the grave.

Basil started to his feet, staring from the Moor to Hormazd.

"Dead—" his pale lips stammered. Then, turning to his dark companion, he added by way of encouragement to himself:

"You gave me truth!"

Daoud was cowering on the floor, his eyes staring into the shadows, where hovered the Persian's almost invisible form.

A nod from Basil caused him to rise.

"Away with it!" shrieked the Grand Chamberlain overcome with terror. "See that no one sets eyes upon it!"

The Moor wrapped the severed head into the blood-stained cloth and darted from the chamber.

Then Basil turned to his visitor.

"In six days Rome shall hail a new master! Let then the sable banners of Hell be unfurled and the Nameless Presence rejoice upon his ebony throne! And now do you come with me into the realms of doom that gape below, that your eyes may be gladdened by that which is in store for you!"

Taking up a torch, Basil lighted it with the aid of two flints and the twain trooped out of the chamber into the shadowy corridor leading into the crypts of the Emperor's Tomb.


CHAPTER II
THE ESCAPE FROM SAN ANGELO

Hidden away in some secret vault of the great honey-colored Mausoleum Tristan found himself when the men-at-arms had departed, and he had regained his full senses. Color had faded out of everything. The rock walls were lifeless and grey. The immense silence of the tomb surrounded him. The rayless gloom was without relief, save what sparse light filtered through a narrow grated window so high in the wall that nothing could be seen from below, save the sky.

The torture of it all he could have endured very well. There was something greater. It was the thought of Hellayne. This dreadful uncertainty swung like a bell in his brain, cut through the fibre of his being. And when these thoughts came over him in his lone confinement he beat his hands upon the stone and wept.

They had placed him in a cell, which seemed to have been hollowed out of the Travertine rock. It was small, built in the thickness of the mighty Roman walls. Tristan set his teeth hard, prepared to endure. He knew well enough what it meant. He would be confined in this living tomb till his enemies thought his spirit was broken, and then he would be summoned before a tribunal of the Church.

Once a day, and once only, the door of his cell opened. By the smoky light of a torch, his gaoler pushed a pitcher of water and a machet of bread into his prison. Then the red light died and darkness and silence supervened. Yet it was not the ordinary darkness which men know. Through the haunted chambers of Tristan's mind fantastic forms began to chase each other, evil things to uncoil themselves and raise their heads. More and more drearily the burden of the days began to press upon him. What availed heroic endurance?

But it was not only darkness, nor was it only despair. Nor was it only silence. It was a strange impalpable something which haunted his restless, enforced vigil; a dim inchoate nothingness, that drove him to the verge of madness. Though day draped the sky with blue and golden banners, to tell the sons of men that Night was past and they need not longer fear, for Tristan darkness was not a transient thing, but an awful negation of hope.

All of this Tristan could have endured, had not the thought of Hellayne unnerved him utterly.

She was safe—so he hoped—in the Convent of Santa Maria in Trastevere. But, as hour succeeded hour, his assurance began to pale. Everything had been arranged with the Abbess. But—had she indeed eluded her pursuers? The empty coffin had no doubt long been discovered. Did they believe she was dead, or did the hand who had dealt the blow in the dark, the vigilant eye that had pursued her every step, plot further mischief?

He thought of Odo of Cluny. The monk was influential, but there was, at this hour, in Rome, one even more powerful, and he doubted not but that by his agency the wafer had been placed into his doublet, though the events of that fateful night from the time he had entered the Lateran, were like a black blot upon his memory.

Had Odo even sought admission to his cell? Did he, too, believe him guilty? Had his ears, too, been poisoned by the monstrous lie? To him he might indeed have turned; of him he might have received assurance of Hellayne's fate; and in return he might have reassured her who was pining at the Convent of Santa Maria in Trastevere.

But, was she ignorant indeed of what was happening in the seven-hilled city of Rome? Would not the rumor of the terrible outrage committed at the Lateran knock even at the silent walls of the convent? A captain of the Senator's guard caught red-handed in the perpetration of a crime too heinous for the human mind to conceive!

He reviewed his own life, the close of which seemed very near at hand. Free from cunning and that secret conceit which is peculiarly alarming to natures that know themselves to be, in all practical matters, confounded and confused, he had, in a short time, found himself placed upon the world's greatest stage, a world little fit for dreamers and for dreams. He had been plunged into the inner circles of the mighty struggle, impending between Powers of Light and the Powers of Darkness, upon a sea he knew not how to navigate, and upon whose cliffs his ship had stranded.

One evening, when the cold greyness of an early twilight had enveloped the city, and from the darkening sky every now and then was heard a sound of approaching thunder, Tristan, counting the weary hours of his unbroken solitude, which he could but measure by the appearance and departure of his gaoler, had been more restless than usual. He had hoped to be summoned for early trial before those high in the Church, when, in Odo of Cluny, he would find an advocate, who alone might save him from his doom. But nothing had happened. Nothing had broken the dreary, maddening monotony, save now and then the shriek and curses of a maddened fellow-prisoner, or the moans of a wretch who was dying of thirst or hunger.

Whoever the powers that dominated his life, they evidently had not decreed his immediate death, as if they were rejoicing in the torture of false hopes which each recurrent day waked in his breast, and which each departing day extinguished. The food never varied, and the water intended for the cleansing of his body was so sparse that he had to husband it as a precious possession till the gaoler refilled the bronze ewer on the succeeding day.

When waking from feverish, troubled slumbers, broken by the squeaking of the rats that scurried over the filthy floor of his dungeon, and other presences that caused him to pray for a speedy death from this slow torture, he found himself nevertheless listening for the approach of the gaoler who, after dispensing his bounty, departed as he had come, silent as the tomb, without making reply to Tristan's queries.

Escape, to all appearances, seemed quite beyond the scope of possibility. Yet, with failing hopes, the spirit of Tristan seemed to rise. Had not his good fortune been with him ever since he arrived at Rome? Had he not, by some miraculous decree of destiny, again met the woman he loved better than all the world? And then, they had left him his dagger. After all, not such wretched company in his present plight.

It was on the eve of the third day when the voices of men coming down the night-wrapt passage struck his wakeful ear.

In one of the speakers he recognized Basil.

"And you are quite sure no one saw you enter?" he said to his companion.

"No one!" came the snarling reply. "Nevertheless—they are on my track. I breathe the air of the gibbet which burns my throat."

"And you are positive no one recognized you?" spoke the silken voice.

"No one."

"Take courage, Hormazd. Then there is little danger, yet you should take care that no one may see you. We are surrounded by spies."

"Do you not trust Maraglia?"

"I trust none! You will therefore remain a short time concealed in this subterranean passage."

"Subterranean?"

There was a note of terror in the Oriental's voice.

"That is to say—the vaults! Here you will find honorable and pleasant company, who will not betray you. You will find straw in abundance and each day Maraglia will bring you something to eat. Go slowly. How do you like the abode?"

"Not even the devil can find me here."

"No one will find you here!"

"No one knows where I am," Hormazd interposed dubiously.

"Nor ever shall."

"It is of no consequence. So I am safe."

"You are safe enough. Lower your head and take care not to stumble over the threshold. Here—this side—enter."

"Enter," re-echoed the other. Then there was a pause.

"It is very evident, you are afraid—"

"Afraid? No—but I am thinking we always know when we enter such places—never when we shall leave them."

"How? Did I not say to-morrow night?"

"But if you should not come for me?"

"What profit would your death be to me? Where shall I find another wizard to bring to foretell the death of another Alberic?"

Tristan gave an audible gasp at these words. He felt his limbs grow numb. Had his ears heard aright? Surely they had not. Some demon had mocked him, to drive him mad. Ere he could regain his mental balance, the voice of the Grand Chamberlain's companion again struck his ear.

"But if you should not come, my lord?"

"You could scream!"

"What would that avail?"

"Mind you—I might have to stay here myself for sheltering such a patriarch as you."

"Nevertheless—to guard against all risks—leave the door open—"

He entered, but the door turned immediately upon its hinges.

"My Lord Basil—" shrieked Hormazd, "the door is shut—"

"I stumbled against it."

"Bring a light—open the door—" came a muffled voice from within.

"I shall soon return."

"Do not forget the light."

"Light!—Ay! You shall not want for light,—if what I say be not false: Et lux perpetua luceat eis," chanted the Grand Chamberlain in Requiem measure, as he strode away.

Silence, deep and sepulchral, succeeded. Tristan cowered on the floor, his face covered with his hands. If what he had overheard was true, he, too, was lost. What had happened? Who was the Grand Chamberlain's companion?

Now Hormazd began to scream and rave in the darkness. Terrible execrations broke from the Oriental's lips, as he hurled his body against the iron bars of his prison cell. Demoniacal yells waked the silent echoes. The other prisoners, alarmed and rendered restless, soon joined in, and soon the dark vaults of the Emperor's Tomb resounded with a veritable pandemonium, a chorus of the damned that caused Tristan to put his fingers to his ears lest he, too, go mad.

At nine o'clock that night the last visit was to be paid the prisoners. At nine o'clock Maraglia, the Castellan, came, attended by the guard, which waited outside. The Castellan was in a state of nervous excitement. As he entered Tristan's cell he looked about, as if he dreaded a listener, then he approached his prisoner and whispered something into his ear.

For a moment Tristan knew not what has happening to him. Was he alone with a mad man and was Maraglia too possessed?—

The Castellan, to prove his assertion that he was a bat, began forthwith to squeak, and waved his arms, as if they were wings.

Curious stories were told about Maraglia. No one knew, why he had retained his post so long amidst ever recurring changes, and it was whispered that he was subject to strange possessions of the mind. He faced his prisoner nervously, fingering a poniard in his belt. Tristan watched his every gesture.

A little foam came out of the corners of Maraglia's lips. He wrung his hands and his voice rose into a sort of shriek. He jerked his head half round towards the men-at arms outside in the gallery. The screams of Hormazd continued.

"It is the Ape of Antichrist," he whispered to Tristan. "I have a mind to try conclusions with him. Close the door."

Tristan's wits, preternaturally sharpened in his predicament put words in his mouth which he seemed unable to account for. He had heard rumors of the Castellan. Perchance he might turn his madness to account.

"I can tell you much," he said. "But not here! But one thing I perceive. You are approaching one of your bad spells."

Maraglia shrank back against the door. His face was pale as death.

"Then you know?" he squeaked.

Tristan nodded. The torch which the Castellan had placed in an iron holder that projected from the wall, was burning low and the resinous fumes filled the cell.

"Something I know—but not all! Yet, I believe I can cure you—"

"I am about to turn into a bat! And when I go abroad I scream like a bat—in a thin, high pitched tone. And I flap my arms—and fly away—thus—"

Tristan nodded wisely.

"I know the symptoms—they are of Satan. Nevertheless, I can cure you."

"Without conference with the evil powers?"

Tristan pondered.

"You shall not imperil your soul! But—take heed! It is well that you have spoken to me of these matters. For, from feeling that you are a bat, a bat you will become."

Maraglia was pale as a ghost.

"Then I was just in the nick of time?"

"You are already half immersed," Tristan replied in a deep and menacing tone. "Take heed lest you be utterly drowned."

The Castellan shivered as one in an ague.

"Every Friday at midnight the Black Mass is said by one Bessarion, that is of unthinkable age—a hideous wizard and High Priest of Satan. It is he who has cast the spell over me."

Hope mounted high in Tristan. The alert confidence of his companion animated him and he felt almost as if the great ordeal was over. A distant bell was tolling. Its tones came in muffled cadence into the night wrapt corridors of the Emperor's Tomb.

Nevertheless he shivered at the Castellan's confession. Maraglia, then, was under the spell of this Wizard of Hell.

"I have seen him stalking through these galleries," he turned to his gaoler. "But I possess a spell which renders him harmless. He cannot touch me—nor breathe his evil breath into my soul. I can compel him to take away the spell he has cast over you—that is, if you so wish it."

The Castellan squeaked and waved his arms.

"You would do this for me?"

"If you will not betray me. For only a more powerful spell than that which he possesses can take away the curse he has put upon you."

"Ah! If you would do this! It is coming upon me now. I am going mad. I am a bat!"

And Maraglia squeaked like a whole company of dusky mice, and flapped his arms as if he were about to fly away.

"This very night will I do it," Tristan replied. "But you must help me."

"What can I do?"

Tristan cast all upon one throw.

"Remove your guards from this corridor and leave me a light and a rope."

"It is but reasonable," Maraglia returned. "I will fetch them. When appears the wizard?"

"At midnight! See that I am not disturbed."

Maraglia nodded. Fear had almost deprived him of his senses.

"Last time I saw him he came from yonder corridor," Tristan informed the Castellan.

"That may not be!" the latter replied. "Unless he hath wings. This passage leads to the ramparts."

"It is possible I have been confused by the darkness," Tristan replied pensively. "Nevertheless, I will oblige you, Messer Maraglia."

The Castellan retired with many manifestations of his gratitude, leaving Tristan in possession of a lantern, a candle and a coil of rope.

It was midnight.

The sharp click of a flint upon steel was repeated several times before a spark fell upon the tinder and it caught with a blue, ghostly flicker. There were strange reflections in Tristan's cell. Curious steely lights played upon him.

Then the candle ignited. The glow widened out. Tristan peered about cautiously. The door of his cell had been left unfastened by Maraglia. He had no fear of his prisoner escaping. No one had ever escaped from these vaults, except to certain death.

He crept out into the corridor. It was dark as in the realms of the underworld. The silence of the tomb prevailed. After a time the passage made a sharp turn at right angles. A cooler air blew upon his face, wafted through an unbarred embrasure, beyond which showed a star-lit night without a moon, but not wholly dark.

Drawing himself up into the embrasure he stood at last upon a broad sill of stone. A cool breeze eddied around him. He was at an immense height. A vast portion of Rome lay below. The Tiber seemed like a river of lead. Far away to the left the dark cypresses of the Pincian Hill cut into the night sky in sombre silhouette. He was above the tombs of Hadrian and Caracalla.

Tristan shivered despite himself as he fastened the rope he had secured from the unwary Castellan to the stone ledge. It was not fear; but that actual, physical shrinking, which induces nausea, had him in its grip.

"There is Rome," he said to himself with a savage chuckle.

He made a stirrup loop and curved it round a boss of antique tile, which stretched above the abyss like a gargoyle. Then, with infinite precaution, he lowered the coil of rope.

Dawn was already heralded in the East. A faint grey light appeared in the direction of the Alban Hills. From over the Esquiline came the shrill trumpeting of a cock.

There was a horrible moment as Tristan's hands left the roof edge and he fell a foot to grasp the rope. He curled his legs about it, got it between his crossed feet and began to let himself down. The sinews of his arms seemed to creak. Once he passed an open window and distinctly heard the snores of the men-at-arms who were sleeping within. The descent seemed interminable. As seen from above, had there been any one to watch him, his form grew less and less. From a man it seemed to turn into an ape; from an ape as a night bird groping down the Mausoleum's side; from a bird it dwindled to a spider, spinning downward on a taut thread. Up there, on the height, the rope groaned and creaked upon the curved tile from which it hung. But tile and fibre held. Once his feet rested upon a leaden water pipe and he clung and swayed, glad of a momentary release from the frightful strain upon his arms. That was almost the last conscious sensation. Clinging to the rope he came down quick and more quickly. His arms rose and fell with the precision of a machine. At last he felt his feet upon solid ground, where he reeled and staggered like a drunken man.

He had traversed a hundred thirty-five feet of air.
