"Will Your Majesty leave the matter entirely in my hands?" I suggested. "The police must not be informed."

"It shall be as you wish. I give you authority to act just as you deem best if you really anticipate danger."

"I do anticipate it," I replied, and a few moments later bowed myself out of the Imperial presence.

During that day I idled about the Palace, gossiping with the officials and dames du palais, awaiting the return of the young man Brosch. That night he did not come back, but he arrived at the Palace about seven o'clock on the following morning. The head valet was furious at his absence, but the young man made a very plausible excuse that his sister out at Lichtenberg was very dangerously ill.

I had had no sleep that night, but as soon as I was informed of the under-valet's return, I repaired to the Emperor's study and secreted myself beneath a great damask-covered settee which runs along the wall opposite the door. For nearly an hour I remained there, when the door was opened stealthily and there entered the young man whom I had seen in Hanover on the previous day. He carried a book in his hand. This he swiftly exchanged for another similar book of the same appearance, and a moment later crept out again, closing the door noiselessly.

Quickly I came forth and took up the classical dictionary, a copy of which was usually upon the Emperor's table. It presented just the same appearance as the book that Brosch had taken away, only it was considerably heavier.

Without delay I dashed out, sought the Emperor's valet, and was admitted to His Majesty's presence.

Three minutes later we were both in the study. I took up the book and held it to his ear. Just as I had heard, he could detect the faint ticking of a watch within.

The book had been hollowed out and a time bomb inserted! It was, no doubt, set to explode between eight and nine o'clock, when the Emperor would be at his desk.

"Take it out quickly!" shrieked the Kaiser in terror, when he realized the true import of the plot.

In obedience, handling the book very carefully, I rushed with it downstairs out into the open. I placed it on the grass some distance away, while the Emperor followed me, utterly astounded at the discovery.

Having deposited it, I dashed back to where the Emperor was standing upon the steps, greatly to the surprise of the sentries, when hardly had I reached him than there showed a blood-red flash, followed by a terrific report and concussion—an explosion which, had it occurred in the upstairs study, must have blown the Emperor's head off as he sat.

His Majesty stood white and rigid, instantly realizing what a narrow escape he had had, while the noise caused the greatest alarm, and people began rushing hither and thither to ascertain the cause.

In a few seconds His Majesty was calm again.

"Say nothing of this, Heltzendorff," he said. "Let it remain a mystery. Come upstairs and I will speak on the telephone to the police."

"Your Majesty gave the matter unreservedly into my hands," I reminded him.

"Ah! that is so. I forgot," he exclaimed, and after thanking me he added: "Take what steps you like, but have the offenders punished, and also try to discover who sent me that anonymous warning."

The young valet, who had been, no doubt, heavily bribed by Minckwitz to substitute the book, had already disappeared, and, as a matter of fact, has never been seen in Germany since.

The man Minckwitz had also, it seemed, suddenly left Hanover on the night of my departure, for Hartwieg, following him, reported to me by wire that he was in Paris.

Without delay I travelled to the French capital, saw my old friend Pinaud of the Sûreté, and told him the whole story, explaining in confidence that for some mysterious reason the Crown-Prince feared that if the man were arrested he might reveal something unpleasant.

"I quite understand," replied the French detective, with a smile. "I know that, six months ago, while the Crown-Prince was in Paris, he was one night enticed by a girl into the gaming-house kept by the notorious Minckwitz. There a quarrel ensued, and the Crown-Prince, fearing attack, drew his revolver, which went off and shot one of Minckwitz's confederates stone dead. The Crown-Prince has ever since been paying big sums to hush up the affair. Until recently Minckwitz conceived the idea that if the Emperor died and the Crown-Prince came to the Throne it would mean to him considerably more money each year. Therefore he conceived that diabolical plot. I warned the Crown-Prince of it, and he threatened to expose Minckwitz and have him arrested. Minckwitz, in turn, threatened that if His Highness made the slightest movement to thwart his plans he would expose to the world that the German Crown-Prince, during his latest escapade in the Montmartre, had killed a man. Finding this to be the case, I myself wrote that anonymous letter of warning, which I addressed to the Emperor."

"And which has had the effect of saving His Majesty's life," I remarked.

That night Minckwitz found himself arrested upon a charge of blackmailing a Portugese nobleman, and was later on sentenced to fifteen years' imprisonment.

In his solitary hours in prison he often wonders, I expect, why his dastardly plot failed. Had it been successful, however, it certainly would have had a great effect upon the future history of the world.
