Chasing down clues, Marlowe gets slipped a mickey. Is it related to the crime he’s working on? It doesn’t matter because now, Marlowe is out for vengeance. The bar tender claims to be a fan of the famous Hollywood detective. Philip finds his man, but its too late, Sammy has already been killed.
The trail involves jewel thieves, and a jewel covered lady in a mansion. Before he’s done, Marlowe may also be looking at a thump on the head, but is he going to be on the giving, or receiving end of it?
At gun point, Marlowe is forced to take a long drive to nowhere. A traffic ticket is just the thing to save Marlowe’s life, but he has too many loose ends to wrap up. The trail of thugs seem endless, but at least one provides the clue to rush back to the jewel covered Bessie and her mansion. Answers explode to the surface to put an end to the mystery.
Note: Verna Felton plays both the crusty land lady of the cheap flophouse where Marlowe found his first body, and the ritzy lady with the diamonds. Also the snooty lady in the French jewelry store.
