Sometimes murder extends its reach even beyond the medieval walls of Oxford. So it goes when suburbanites Nick and Honey Addams return home after a night out to find their babysitter, Jessica Lake, dead - her wrists symmetrically bound to the Adams's bed. Her death pose is shocking; more so is Inspector Lewis and DS Hathaway's discovery of fetish photographs featuring Jessica in similar restraints. With Jessica as her muse, the provocative "Oxford type" artist, Marion Hammond, used fetish photography to explore the dual nature of passion: innocence and corruption. In the dark and varied worlds at the outskirts of Oxford, Lewis and Hathaway search for answers in an abandoned children's home, a primate lab, and the upscale home of smug venture capitalist Tom Garland. To piece together the terrifying symmetry of Jessica's murder, Lewis and Hathaway race to solve the mystery of the girl behind the muse.
