Lewis and Hathaway are called in when local businesswoman Andrea de Ritter is brutally bludgeoned to death in an apparent blackmail plot gone wrong. But if that's true, why is MI5 involved-and why won't they help?

In the run-up to an election at Oxford's prestigious St Gerard's Hall, the college is shocked by a string of brutal murders, someone seems to be picking off the candidates one-by-one. As Lewis and Hathaway investigate further, they become embroiled in a revenge tragedy which began thirty years ago.

Oxford's last surviving all-female college is bidding farewell to one of its most prominent professors, and a leading light in the feminist movement-but not before Lewis and Hathaway are called in to investigate two murders that may be linked to the college and its decade-old secrets.

Dr. Hobson finds herself caught up in a decades-old vendetta when one of her university friends is murdered, and another young student is killed in the house Hobson and her friends shared years ago. Obviously unable to act as the pathologist in the case, Hobson instead finds herself and her remaining friends—Dr. Ellen Jacoby and playboy Alec Giles (Rupert Graves, Sherlock)—suspects, and Lewis is forced to subject her to questioning.
