Edgar Marsh, a shy librarian obsessed with erotica, becomes infatuated with his neighbour Betty Clare when he sees her undressing in her bedroom. He invites her to dinner, and although she clearly is uncomfortable with the attention he pays her, he showers her with jewelry and fantasizes about their future. Complications arise when he introduces her to his friend Carl Loomis, whom Betty finds far more attractive and appealing. After witnessing Carl and Betty together in her bedroom, Edgar bludgeons Carl to death with a poker and buries him beneath the floorboards in his piano room. His overwhelming guilt leads him to believe a ticking metronome and the incessant dripping of a faucet actually are the sound of his victim's heart still beating.
Around the time the film was produced typical budget of the Danzigers' feature film was £15,000. This cost a little more due to its period setting and necessitated shooting in black and white.[5]
Critical reception
The Monthly Film Bulletin wrote: "A modest but surprisingly effective little film, which contains much more genuine Poe atmosphere than many a more ambitious adaptation of this tale, despite the alterations which mean that the story is now a dream, with a vicious circle ending strongly reminiscent of Dead of Night. The shoestring sets and lighting, in fact, contribute enormously towards achieving the correct oppressive aura of dank, seedy, gaslit Victoriana. Excellent playing by Laurence Payne, Adrienne Corri and Dermot Walsh, from a script which concentrates intelligently on establishing a credible triangle relationship before moving into the horror, creates three-dimensional characters of real interest. There are, to be sure, one or two purely conventional horror-film gimmicks – lightning zigzagging across the sky at a moment of crisis – but on the whole it is done imaginatively (if not very originally) rather than crudely. The tell-tale heart itseif is particularly effective, where the whole house – the pendulum of a clock, a dripping tap, a ticking metronome, a swinging chandelier, a piece fallen from a chess-board and rolling gently back and forth – seems to pick up and magnify the terrifying beating rhythm which haunts Edgar."[8]
