A vicious murder is committed, but who has blood on their hands?

On a hot summer's afternoon, Michelle Wentworth enjoys a rare few hours of relaxation. Sunning herself by her pool, she sends her lazy teenage son to fetch her a drink. But instead of a refreshment, Michelle is given a nasty shock when shortly after her child's bludgeoned body is discovered on the doorstep.

DI Annie Delamere attends the scene, joined by DS Zoe Everett. There is nothing to suggest a motive or perpetrator. They dig into Michelle's life and come to suspect she may have been the target.

When another battered body is found, Annie finds that every clue leads back to a dispute at Michelle's business. But with so many people with reason to seek revenge, will Annie and her team look in the right places – or will it be too...
