is unfaithful,
whom can I trust?"

"You must not cease to trust him entirely, yet, monsieur," I replied.
"The charge against him is based upon evidence that may be disproved;
but my drag net is out to-night, and the dawn will see nearly every
nihilist in St. Petersburg in prison, or on the way out of Russia. If
you had been prevailed upon to detain me I tremble for what might have
happened."

"Tell me----"

"Do not, I beg of you, detain me now, monsieur. Every moment is
precious. My men are swarming over the city, and even now the prisons
are filling up. I must get to work, for this is a matter to which I
must personally attend."

"And Michael?"

"Leave him where he is, in his apartments, until I return."

"When will that be?"

"Soon after daylight."

"Then come to me at once. Have me awakened if I am sleeping; but I
shall not be."

"I will do so."

"One word more. What of the princess?"

"She would have been murdered to-night by the nihilists had I not
arrested her as one, conducted her through the prison, and thence on to
the house of the prince."

"Why did you not bring her here and place her in my care?"

"She would not wish to come here, monsieur. Princess Zara once had a
lover who became crazed, and was killed here in the palace by one of
the guards, I believe, so----"

"Yes--yes, I understand. You did right. Stop! One word more before you
go. This conspiracy to which you referred, against the whole royal
family; are you sure that you have got at the root of it?"

"As sure as I am that I am here in the presence of the Czar of Russia."

"You have never failed me yet, Derrington;" and he grasped me by the
hand.

"And I never will, monsieur."

"Well, go. I shall expect you soon after daylight."

In reality there was little for me to do that night, more than I had
already done, and yet it was impossible that I should be shut up in the
palace with so much taking place throughout the city, immediately under
my direction, and over which it was imperative that I must retain
supervision. I knew that there would be frequent demands upon me for
authority to do and perform certain things, and it was important that I
should be on hand. I was always provided with the necessary papers for
anything in the official line that I might be called upon to perform.
This had been arranged in the beginning, the better to preserve the
secret of my business in St. Petersburg. I had innumerable imperial
passports
