A hated dictator, living in exile in Miami, is murdered during a birthday party for his son. Lt. Snedigar thinks he has an open-and-shut case against Pepe the Clown, who performed at the birthday party, but Pepe insists he was not at the party. Dave has to prove to the skeptical policeman someone else went to the party in Pepe's costume.

A former USO singer who knew Dave in Korea is trying to make a name for herself. To help, she gets a ""gimmick"" - $130,000 worth of jewelry to attract publicity. The ""gimmick"" indeed attracts publicity -- thieves, who rob the nightclub during the show.

When Ken inquires as to why his partner left the Boom Boom Room in an angry huff, Dave says he saw a man he wanted to kill. The man in question is Bernard ""Chilly"" Childress, a ruthless criminal whom Dave once unsuccessfully prosecuted in New York, and who was responsible for Dave once being shot in the chest. Lt. Plehn has word that Childress is planning on moving to Miami, so Dave sets out to do what he failed to do in New York: finish off Childress.
