The hotel manager, Mr. Jones, took you to the scene of the tragedy. Wealthy industrialist Albert Krubb lay in a pool of his own blood near the sofa. The means of murder lay right there - the bloody Knife lay in Krubb's hand, giving the appearance of suicide. Jones spoke, pointing to the body.

Mr. Jones: "Our maid, Miss Susie Valenstein, found him while cleaning after smelling an unpleasant odor from his room. Mr. Detective, tell me, was it murder or did Krubb kill himself?"
