“Yes; tried to enter at the middle door, where I had seen the men.”

“And next?”

“Finding that door fastened, I tried the third, because the men had seemed to disappear in that direction.”

“The third room was also locked?”

“Yes; or at least the door would not open from the outside. Then I went back to the door number one.”

“And that opened at once?”

“Yes; had I tried that first, I should probably have seen the men,—or the girl, Jenny.”

“Perhaps. Could you recognize the head of the visitor if you should see it again shadowed on the door?”

“I am not sure, but I doubt if I could. I could tell if it were a very different type of head, but if merely similar, I could not swear it was the same man.”

“H’m. We must make the experiment. At least it may give us a hint in the right direction.”
