When he thinks he's about to keep an important business appointment in lawyer Lamar Madison's cramped Phoenix law office HERB NASH finds himself shaking hands with a homicide detective who suspects them both of brutally murdering James Olivette, aka Jim B-small time con-artist and only son of one of the city's wealthiest widows. The detective tells them Jim B's dismembered body parts were discovered earlier that morning splayed around a storm drain in the heart of an exclusive Camelback Mountain neighborhood. It gets personal for HERB NASH when the detective tells them both that their business cards were found tucked inside the dead man's shirt pocket, making them the only "persons of interest" and potential suspects in the Jim B murder investigation.
