Police Trap #6

Police officers use one-way windows to observe evidence and catch criminals without their knowledge. A man named Harry Carpenter, a robber and thief, is arrested after being recognized at a police station, having previously stolen money from a pocketbook. Under interrogation, Carpenter admits to keeping the stolen bills but claims he saved the change from tips and his wife's birthday money to justify possessing the cash. When confronted with a witness who saw him at a holdup, Carpenter refuses to confess or provide a description of the killer, forcing the detective to employ psychological pressure tactics to extract the truth from the reluctant suspect.
