"A murderer hidden in plain sight"--Cover.

Is it possible to forget that you've committed a murder? When Cassie Fitzgerald was at school in the late 90s, she and her friends killed a fellow student. Almost twenty years later, Cassie is a happily married mother who loves her job-as a police officer. She closely guards the secret she has all but erased from her memory. One day her husband finally persuades her to go to a school reunion. Cassie catches up with her high-achieving old friends from the Manor Park School-among them two politicians, a rock star, and a famous actress. But then, shockingly, one of them, Garfield Rice, is found dead in the school bathroom, supposedly from a drug overdose. As Garfield was an eminent-and controversial-MP and the investigation is high profile, it's headed by Cassie's new boss, DI Harbinder Kaur, freshly promoted and newly arrived in London. The trouble is, Cassie can't shake the feeling that one of them has killed again. Is Cassie right, or was Garfield murdered by one of his political cronies? It's in Cassie's interest to skew the investigation so that it looks like it has nothing to do with Manor Park and she seems to be succeeding. Until someone else from the reunion is found dead in Bleeding Heart Yard.
