Rachel Innes, a middle-aged spinster, has barely settled in at the country house she has rented for the summer when a series of bizarre and violent events threaten to perturb her normally unflappable nature. A strange figure appears briefly in the twilight outside a window. At night, a rattling, metallic sound reverberates through dark halls, and - most disconcerting of all - the body of a strange man is found lying in a pool of blood at the bottom of a circular staircase.
Before this spine-tingling tale ends, five connected deaths shatter the normally placid atmosphere of the vacation retreat. Rachel's devoted niece and nephew are among the prime suspects in one of the murders, stolen securities and a bank default threaten the young pair's financial security, and Aunt "Ray" ultimately fights for her life in an airless secret room.
