When Danny Miller, a retired dentist, is murdered for no apparent reason, and the police begin their investigation, Johnny "Clubs" Murdock is hired to observe and report on the progress of the investigation. Without trying he becomes more and more involved until, more by luck than by design, the truth, as clear as any truth can be, comes to light.
Johnny Murdock's business is making inquiries about people's lives and habits. He would tell you, for example, that memories are determined by perspective but are also shrouded by the fog of age. He would also tell you that an all-important notion of honor is hard to define and changes over time. He might add that a strange mixture of honor and the fog of age is sometimes deadly.
