Jeff, a private investigator from L.A. and friend of the SurfSide detectives, is called to Miami to investigate a threatening note left for a lounge singer. He meets a redhead, who takes him to her home. He passes out and wakes up the prime suspect in the murder of the redhead's husband, leaving his SurfSide friends to clear him.

Someone is trying to kill a former boxing champion, so his manager hires Ken to find out who is behind the ""accidents"" (including a bomb placed at SurfSide 6 during a party for the champ). Ken finds no shortage of suspects, including the boxer's ex-wife, a crusading sports writer, and a mob boss who owns the boxer's contract.
