THE house had been barred, locked and shuttered for over eleven years. Lying awake at night in the adjoining house, Elizabeth Featherstonhaugh used to think she heard strange noises in the old empty house—sounds of tappings, creakings, rumblings, footsteps where there were no feet, drawers pulled open where there were no hands, furniture thudding from spot to spot. The two weeks that remained before the house was to be reopened were weeks shot through with terror and menace. For Elizabeth's very presence in the household of Captain Pewter was a threat to the plans of a murderer who had already killed two women and would not hesitate to kill again! This tense, baffling novel is the mystery upon which Paramount's smash movie hit, "The Unseen," was based.
