Perry Mason

Cmdr. James Page is the Project Officer for the testing of some electronics equipment for the Navy submarine, Moray. Cmdr. Jerome Burke is assisting the police in the investigation of the murder of a cafe singer. The police believe an unknown sailor on the Moray may be responsible. Cmdr. Page has found out that his father-in-law, Anthony Beldon, owns Alpha Electronics, the manufacturer of the electronics equipment he is testing. Cmdr. Page feels there could be a conflict of interest. On the day of the testing, Cmdr. Page is found dead in the captain's quarters. Robert Chapman, a sailor, is accused of the murder when he is found to be the husband of the dead cafe singer and his shoes contain pieces of broken glass found at the scene of her murder.
