When a detective is called in to help in a private matter, he does not normally expect to be asked to clear up the mess left by a gory murderer so as to keep the whole thing quiet from the police. In the normal way, Keyes wouldn't have agreed, but just as the beautiful Miss Wiseman had a reason to keep the murder quiet, so the detective had a reason to do as he was asked. But that didn't stop natural inquisitiveness enticing him into further trouble.
