"You are sure of that?" "Perfectly." "Did he see you?"' "I think not. I was standing right at the corner of the two halls. The man came out and glanced around, but I stepped back quickly, because we do not like to appear to spy upon our guests. He did not see me." "What did he do?" "He went out the front way. I supposed the lady went with him, for I was sure that I heard the rustling of her dress." "Where was Corbut then?" "In room A." "How long did he stay there?" "Only a minute. I went back to the desk, and then was called by a waiter upstairs. Just as I turned to go I saw Corbut coming through the hall." "Did you speak to him?" "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."
