Mister Mystery #5

In "The Thirteen Locks!", Dennis Langley's sinister scheme to inherit his foster-mother's fortune takes a chilling turn when he impersonates her late husband, Jeffrey, using a haunting Italian opera tune. With the help of his crooked psychiatrist friend Drake, Langley pushes his plan forward—until Jeffrey's corpse suddenly appears, shattering their deception. Art by Walter Palais brings the eerie tension to life, while the cover by Tony Mortellaro captures the story’s unsettling mood.
