“But the police cannot touch me; I have no fear of them,” I remarked, just as a thought suddenly occurred to me.

Where was my passport, that paper without which no one in Russia is safe, not even Russians themselves? I took up my coat and felt in the inner pocket where I constantly kept it.

My valise, the pockets of other coats, every hole and corner I investigated, but found it not. It was evidently lost or stolen!

“No, I will not,” I cried angrily. “I see this is a plot to extort money—or something. My passport has been stolen, and I shall myself inform the police to-morrow, and also of my suspicions regarding this house.”
