The queer complaint comes from Major Henry Rodman (Roger Maxwell), who claims to have witnessed a murder through a neighbor's window, depicting a pair of gloves that shoot a man dead. A more eccentric neighbor, Baron Novakov (Bernard Rebel), confirms that he definitely heard two gunshots, not the sound of a car backfiring.
Colonel March and Inspector Ames (Ewan Roberts) call upon the young couple who reside there, Jim Hartley (Anthony Forwood) and his wife Betty (Patricia Owens), who show off a portrait of the murder victim, Jim's uncle, who has been deceased for four years. Seeing no corpse, no blood, and no evidence of wrongdoing, the Major apologizes for his apparently crazy story, but Colonel March refuses to give up easily, buying time until the pieces fit the puzzle.
