Case for Three Detectives (1936) by Leo Bruce was perhaps the first impossible crime novel I read after becoming aware that the subgenre existed, and it had such a marked effect on me that, nearly 15 years later, it was the first title added to my Locked Room Library. Revisiting it is, then, something I approached with trepidation: I have experience of beloved texts failing to live up to my memories…but, then, I’ve reread books I enjoyed and found them even more delightful on more than one occasion. So forward I sallied into this: a weekend gathering, a locked room throat-slashing, and the usual rounds of suspicion and obscure proclamations from three genius amateur detectives.
