"You can spare the time now, I suppose?" he said inquiringly with a grim glance at the valentine hanging from the improvised hook.

Paul saw that his ruse was discovered, but he followed the spy into the front room, his heart beating high with expectation.

"There is never an effect without a cause, young man," remarked Poubalov, motioning Paul to a chair; "the effect was sufficient for me last night, and so far as your act deserves it, you have my thanks. This morning I sought the cause, and of course, I found it. Do not be disturbed. I have no reproaches to make. You imagined yourself at war with me, and you took your own methods to win. There is nothing to complain of in that; but you, as a Russian of intelligence, should have known that I could not be as hostile as you think to an American citizen. Bah! it's not worth discussing! You've all lost your heads.

"What I have to say is this: I am on duty for the czar, and having recovered from my dangerous temptation to be derelict, I shall do what duty demands, without let or hindrance from anybody. I will tolerate no interference, no matter whose fair lips give the command. When that little wretch, Litizki, was in that chair where you are now sitting, I sought to influence him by threats against himself. I don't take that method with you, Paul Palovna. If you choose to do so, you can dog my footsteps from now on, for I presume your American laws will not protect me in my desire to work undisturbed; but bear in mind that I have no more love for Ivan Strobel now than I ever had, and if I see fit to release him, it must be I, Alexander Poubalov, who chooses to do so of his own free will. Do you understand me?"

"Sufficiently to see that you would frighten me from my course by threats against the man whom you have in your power, and whom I am trying to rescue."

"You do well," continued Poubalov; "and if you are in any doubt as to whether I am in earnest, I advise you to report what I have said, and what you saw in this room last night, to Miss Hilman. She will tell you whether I am likely to be gratuitously merciful. Spy upon me, therefore, if you like. I shall know that you defy me, and you will have to bear the consequences. Shall we breakfast together, Paul Palovna?"

Paul ignored the ironical invitation, which was Poubalov's way of saying that he has said his say, and remarked:

"I also have a suggestion to make."

Poubalov raised his brows in contemptuous surprise that anything could be added to his statement of the situation.

"You have spoken of American law," said Paul, "and I simply suggest that the friends of Strobel may to-day resort to law to obtain his freedom. I don't know how much you may have said to Litizki and Miss Hilman, but you have made some damaging admissions to me."
