“I do not dispute that,” I said. “But I was discussing the highly interesting career of this Danilo Danilovitch. If there is any attempt upon Her Imperial Highness the Grand Duchess Natalia, as you fear, it will be by that individual. General. Therefore I would advise your department to keep close observation upon him. He is lodging at Number 30B, Blurton Road. And,” I added, “if you should require any further particulars concerning him, I daresay I shall be in a position to furnish them.”

“Why do you suspect him?”

“Because of information which has reached me—information which shows that it was his hand which launched the fatal bomb which killed the Grand Duke Nicholas. His Imperial Highness was actually killed by an agent of Secret Police! When that fact reaches the Emperor’s ears there will, I expect, be searching inquiry.”

“Have you actual proof of this?” he asked in a thick, hoarse voice, his cheeks paler than before.

“Yes. Or at least my informant has. The traitor was recognised among the crowd; he was seen to throw the bomb.”

General Markoff remained silent. He saw himself checkmated. His secret was out. He had intended to raise a false scare of a probable attempt at Brighton in order to terrify me, but, to his amazement, I had shown myself conversant with his methods and aware of the truth concerning the mysterious outrage in which the Grand Duke Nicholas had lost his life.

From his demeanour and the keen cunning look in his steely eyes I gathered that he was all eagerness to know the exact extent of my knowledge concerning Danilo Danilovitch.

Therefore, after some further conversation, I said boldly:

“I expect that, ere this, the Central Committee of the People’s Will has learned the truth regarding their betrayer—this man to whose initiative more than half of the recent plots have been due—and how he was in the habit of furnishing your department with the lists of suspects and those chosen to carry out the outrage. But, of course, General,” I added, with a bitter smile, “you would probably not know of this manufacture of plots by one in the pay of the Police Department.”

“Of course not,” the unscrupulous official assured me. “I surely cannot be held responsible for the action of underlings. I only act upon reports presented to me.”
