Several people on my Goodreads list love that book, as well as his previous one The 7½ Deaths of Evelyn Hardcastle.
Aiden Bishop knows the rules. Evelyn Hardcastle will die every day until he can identify her killer and break the cycle. But every time the day begins again, Aiden wakes up in the body of a different guest at Blackheath Manor. And some of his hosts are more helpful than others. With a locked room mystery that Agatha Christie would envy, Stuart Turton unfurls a breakneck novel of intrigue and suspense.
I want to read them, but my queue...sigh. Library books first because they have a time limit.
