Carver's internationally bestselling debut thriller features a very different kind of serial killer.

A shocking double-murder scene greets Detective Inspector Philip Brennan when he is called to a flat in Colchester. Two women are viciously cut open and lying spread-eagled, one tied to the bed, one on the floor. The woman on the bed has had her stomach cut into and her unborn child is missing. But this is the third time Phil and his team have seen such an atrocity. Two other pregnant women have been killed in this way and their babies taken from them. No one can imagine what sort of person would want to commit such horrible crimes.

When psychologist Marina Esposito is brought in, Phil has to put aside his feelings about their shared past and get on with the job. But can they find the killer before another woman is targeted?
