Mr. Kesselbach stopped short on the threshold of the sitting–room, took his secretary's arm and, in an anxious voice, whispered:
"Chapman, some one has been here again."
"Surely not, sir," protested the secretary. "You have just opened the hall–door yourself; and the key never left your pocket while we were lunching in the restaurant."
"Chapman, some one has been here again," Mr. Kesselbach repeated. He pointed to a traveling–bag on the mantelpiece. "Look, I can prove it. That bag was shut. It is now open."
Chapman protested.
"Are you quite sure that you shut it, sir? Besides, the bag contains nothing but odds and ends of no value, articles of dress. . . ."
