Actually a presentation of the Mystery Playhouse, and introduced by Peter Lorre. Details of an inheritance, blackmailers, gamblers, and a private detective all emerge.
At the mansion of the eccentric family, detective Pierce has plenty of shady characters to choose from, while sifting out who might be the guilty party. Will he be making a payoff to the blackmailers? Or falling prey as a pawn in some kind of cover up for murder?
The plot thickens when bodies pile up. Jonathan Pierce and his girlfriend put the heat on the gambler, and others in the house as he digs for clues, and hopes to crack the shell of the killer.
Clues explode to the surface, and Jonathan is certain he can solve this case, but will he be in time to keep the cops from arresting the wrong man? In classic mystery novel fashion, and with high dramatic flare, the loose ends are tied up, the mystery exposed, and the real crook is handed over to the cops.
