In this DI Helen Grace a friend of hers ends up dead and she is rattled. As the bodies keep appearing, each with a connection to her, Helen gets more and more nervous. Someone is trying to send her a message but she can't figure out who. Nerves are stretched thin, tensions are high, and Grace falls under suspicion for the murders. There's two ways this can end and she's hoping it will be in her favor.

I love this series by Arlidge. His continued development of DI Grace and the secondary characters is fantastic. His storylines are terrifying - I really hope they aren't based on real cases.
