The 7 1/2 Deaths of Evelyn Hardcastle

Agatha Christie mixed with Quantam Leap.

Stuart Turton, the author, is a fan of Agatha Christie mysteries and the show Quantam Leap and it's easy to see their influence in The 7 1/2 Deaths of Evelyn Hardcastle. It's a closed-circle mystery turned on its head.  Aiden Bishop has 8 days to figure out who killed Evelyn Hardcastle.  But instead of questioning suspects after the murder, he relives the same day, with one day in a different person's body.  All the while, he's trying to avoid being murdered himself by the evil Footman.  This is a mind-bending, and genre-bending, mystery thriller.
