Gunshots were heard inside Goldblat’s shop, and little Joey has to get inside the locked office with the help of Carman and a cop on his beat. Is the killer still inside? Is it possible that the killer shot the Upholsterer, and vanished from the locked room without a trace? Join Casey in the Blue Note as he talks with Ann Williams and Ethylbert about what the police have determined thus far.
At the police station, Casey again reviews all the clues that set the scene with the locked door mystery with the cops. Who had motive to kill Goldblat? Is the murder linked to other gang killings in town? Though the cops are stumped, Casey has an idea that the upholstered furniture stacked against the door holds a clue.
Sharing his theory with Ann, Casey goes on the trail of his suspect. They pose as a couple who are interested in renting a room in a boarding house. Is there hidden treasure, or loot of some kind hidden in the furniture? Is Mrs Potter, the boarding house matron as innocent and clueless as she appears?
Back in the Blue Note, Casey shares all the secrets of the case with Ethylbert.
