“It may be,” answered the concierge indifferently. “En effet, I have not seen him for several days.”

Stroeve ran up the stairs ahead of me, and when I reached the top floor I found him talking to a workman in his shirt-sleeves who had opened a door at which Stroeve had knocked. He pointed to another door. He believed that the person who lived there was a painter. He had not seen him for a week. Stroeve made as though he were about to knock, and then turned to me with a gesture of helplessness. I saw that he was panic-stricken.

“Supposing he’s dead?”

“Not he,” I said.

I knocked. There was no answer. I tried the handle, and found the door unlocked. I walked in, and Stroeve followed me. The room was in darkness. I could only see that it was an attic, with a sloping roof; and a faint glimmer, no more than a less profound obscurity, came from a skylight.

“Strickland,” I called.

There was no answer. It was really rather mysterious, and it seemed to me that Stroeve, standing just behind, was trembling in his shoes. For a moment I hesitated to strike a light. I dimly perceived a bed in the corner, and I wondered whether the light would disclose lying on it a dead body.

“Haven’t you got a match, you fool?”

Strickland’s voice, coming out of the darkness, harshly, made me start.

Stroeve cried out.
