The 7½ Deaths of Evelyn Hardcastle by Stuart Turton

The novel follows a protagonist named Aiden Bishop who must solve the murder of Evelyn Hardcastle at an English country estate. However, each day he wakes up in the body of a different guest, and the murder repeats in a time loop until he identifies the killer.

The novel is not by or directly connected to Agatha Christie, but it is heavily inspired by her style of country-house murder mysteries. Stuart Turton blends the classic Christie whodunit format with a time-loop and body-swapping narrative structure.

Many readers find the novel complex because the protagonist inhabits multiple characters' bodies across repeating days, requiring careful attention to the timeline. The book includes a character map and notes to help readers track the overlapping events.

Stuart Turton published a follow-up novel, The Devil and the Dark Water, in 2020, though it is not a direct sequel. A television adaptation of Evelyn Hardcastle has been reported to be in development, though details have been limited.
