Christopher Fowler
Bryant and May, Fowler’s irascible, crabby and ancient detectives totter through this wonderful series. Set in London, the detectives and their “Peculiar Crimes Unit” investigate offbeat murders. The books are wonderfully filled with details about historic London, esoteric religions, hidden underground spaces, cults and creepy post-mortem anomalies. Do read them in order starting with Full Dark House, as there are some giveaways in later books.
