The Seven Deaths of Evelyn Hardcastle
by Stuart Turton.
How to do this dark jewel of a book justice? An Agatha Christie-esque whodunnit set in a sinister stately home in the 1920s, featuring a Groundhog Day time loop and Quantum Leap-style body-hopping. The plot: tormented Aiden Bishop is trapped in the various bodies of the inhabitants of Blackheath House, doomed to relive the same day over and over again until he solves the murder of Evelyn Hardcastle. Thrilling, addictive, genuinely terrifying, utterly original and mind-fizzingly ingenious… I cannot do it justice, and nor can I get it out of my head.
