The Unkept Woman

The friendship of Gwen Bainbridge and Iris Sparks, the “intelligent and resourceful” owners of the Right Sort Marriage Bureau, is tested in Montclair’s exemplary fourth mystery set in post-WWII London (after 2021’s A Rogue’s Company). When someone is shot to death in Iris’s flat, where an ex-boyfriend of hers has been living as a renter, Iris’s ability to be fully frank with Scotland Yard is limited by the connection of the victim to her previous life as a British intelligence operative. Iris decides to investigate on her own and asks Gwen to help search for the killer. The case comes at a fraught time for Gwen, who attempted suicide in 1944 after learning her husband was killed in battle; she was subsequently institutionalized in an asylum. Gwen is in the process of petitioning to end the guardianship controlling her life, which could be jeopardized if she once again probes a murder. The solution to the crime is both surprising and fair to the careful reader. Montclair’s capable, funny, and fully developed leads set a gold standard for the amateur sleuth subgenre. Dorothy Sayers’s fans will hope this series has a long run. (July)
