"Yes; I called to him to stay by the desk while I went upstairs."

"Did he answer?"

"Yes; he said 'very well.'"

"And that's the last you saw of him?"

"Yes."

"All right; so much for Corbut. Now for the two men. Would you know them?"

"Not the man in room A. I didn't notice him particularly."

"But how about the man who came out of this room? He's the one we're after."

"I would know him," said Gaspard, slowly. "Yes; I feel sure that I could identify him."

"That's good. Now for the crime itself. Go back to the desk and ring for a messenger. When he comes, send him here. Don't let anybody else come, and don't say a word to anybody about this affair."
