"Yes, it's an abandoned tavern—that is, it was formerly run as a hotel, but the enterprise was a failure, and it is now closed. I learned that much from a man who was passing while I stood under the balcony, waiting for somebody to answer my ring. He remarked that he didn't believe I'd find anybody at home, as the house had been practically deserted for some time."

"But we saw Poubalov come out of there this morning," urged Clara.

"I said as much to my informant, but he answered that it was probably somebody who had been looking it over with a view to purchase. Of course we know better, but it goes to show that neither Patterson nor anybody else lives there."

"Except Ivan, if he still lives," said Clara gravely.

"Don't think I forgot that possibility," returned Paul, earnestly. "I quietly tried the door after my informant had passed on; he didn't know the name of the owner, by the way. Of course the door was locked. I went around to the side and back, for there is a driveway there leading to stables that are apparently as little used as the tavern itself. Every door and every window was closed. I knocked and shouted, and then neighbors put their heads out of windows and advised me that I was making a noise to no purpose. If it had been night I would have burst open a door or window, and have gone through the house from roof to cellar, but that plan is rather impracticable by daylight."

"I wonder," said Clara, "if the law would allow a search of that building. I mean something to be done officially. I've heard of search-warrants."

"It's barely possible, and you might try it; but my idea, such as it is, would be to go there quietly to-night ourselves, and force an entrance."

"And in either case Poubalov might return during the day, and effect a change in the situation that would make the search useless."

"Yes," said Paul, gloomily, "I had thought of that."
