Once started, however, my suspicions gathered like snow flakes in a drift, and quickly hardened into certainty. Everything seemed to be as highly charged with doubt, as a bomb with dynamite. I could see how I had just played into their hands, like a countryman in the care of a gang of sharpers.

Why should Bremenhof give in about Madame Drakona; and to me of all men? He had cunningly led me to believe that it was because of my changed relations in regard to Volna. But mine were little more than blank cartridges; yet he had waved the white flag the instant I fired one at him.

I could see now how unreal the whole interview had been. He had read my purpose and had just played with me, keeping his own plan cunningly concealed. He meant to use me for that plan. What was it? And how did he mean me to help him?

There was the matter of Felsen, too. Why had Bremenhof been at the pains to render me a service? I had not been so dense as not to notice that his indifference in mentioning Felsen was feigned. What object had he in sending the man back to me at such a moment?

I recalled the interview I had overheard between Felsen and the police agent at Bratinsk. The police had brought him to Warsaw now. What had been the relations between them in the interval? Were they going to use him as a spy? It looked very much like it.

Then I thought of Burski and grew hot with shame at the easy manner in which I had let the fellow trick me with his use of the Fraternity signal and pass words, and his offer to let me escape. He had been fooling me of course; and had succeeded with his subtler effort after his superior at Ladislas’ house had failed. It was all part of the system of spy work: and by this time Bremenhof knew everything and was no doubt laughing at me and setting the snare which was to complete my overthrow.

Sackcloth and ashes may be hard wearing apparel; but they don’t hurt as much as the stings of such humiliation as I felt in realizing my self-satisfied stupidity and the ease with which I had been gulled.

The one redeeming point was that my eyes had been opened before it was too late; and the question was whether I could still get out of the mess into which I had blundered.

I soon guessed the drift of Bremenhof’s scheme. It was to ruin me by convicting me of complicity in the Fraternity conspiracy; and in the meanwhile to use me to enable him to find Volna. Felsen was no doubt the chosen spy for the latter part; and Burski for the former.

My first step was obvious. I must not let either man know that I suspected him.
