When a serial killer stalks a sleepy English village, a Scotland Yard detective must search for clues among terrified townsfolk in this classic mystery.
Samuel Bracknell is found dead in his home with a knife in his back. It's the third murder of its kind in as many weeks, and the residents of Carleton Unthank are left shaken. When Superintendent Littlejohn learns that all three crimes were committed with the same knife, a disturbing question arises: why, then, was the knife left in Bracknell's body?
When a fourth body turns up, this one an apparent suicide, Littlejohn is baffled. This once quaint village is gaining a ghoulish reputation. As the threat of murder looms each time the sun sets, Littlejohn must face sleep-deprived residents, no clues, and a race against the clock to prevent the body count from rising any further.
