When You Are Mine

A heart-pounding psychological thriller about friendship and obsession

Philomena 'Phil' McCarthy is a promising young officer in the London Metropolitan police.

But everything changes when she is called to the scene of a domestic assault. Unbeknownst to her, the abuser is a decorated detective and Phil's efforts to protect his girlfriend - Tempe Brown - from violence result in Phil being unjustly struck from the force.

In the fallout, Phil begins to teach Tempe self-defence and they strike up a tentative friendship. Tempe is thoughtful and sweet, and within a matter of weeks the two women are inseparable - talking, socialising and confiding their deepest secrets in one another. But something isn't right. Sinister things keep happening and, when a body is discovered, Phil realises that Tempe is hiding deadly secrets of her own. Secrets she is willing to kill for . . .

This pulse-racing standalone psychological thriller from the internationally bestselling author of The Secrets She Keeps is Michael Robotham's finest yet, and confirms his reputation as the Mastermind of Crime.
