In this episode of The Adventures of Philip Marlowe, a simple phone mix-up drags the detective into a deadly scheme involving crossed wires, a frantic woman, and a killer who lives just down the hall. When Marlowe discovers that his neighbor’s calls are bleeding into his own phone line, he overhears a desperate message from a woman named Rina—one that leads straight to a murder tied to an embezzlement job gone bad. The neighbor, a quiet man named Arthur Minter, turns out to be anything but harmless. He and Rina’s husband, Ernie, pulled a heist together…but Ernie tried to double-cross them and wound up dead. Now Minter wants the stolen money—and believes Marlowe knows too much. As Marlowe dodges a gun at his ribs, an overly talkative neighbor, Miss Garrity, accidentally gives him the opening he needs. With a few fast moves and some improvised timing, Marlowe turns the tables on Minter and uncovers the truth: Rina ran because she thought both men were trying to kill her, never knowing her husband had already met his end. In the final showdown at the Hollywood Library, Marlowe corners Minter and exposes the whole plot—another reminder that in an apartment building full of strangers, your closest neighbor might be the one planning your funeral.
