A man is shot dead and his body is dumped on the moors. His arm is stamped with the Chinese symbol for ‘sorry’. There have been five unsolved murders with the same hallmark. The police can’t find any motive or connection between the victims.

Bella Richards was close to the murdered man. She lives with her five-year-old son and has begun a new life in the local area. But although clearly grief-stricken, she is not telling the police everything she knows.

Detective Talbot Dyson wants his most trusted inspector on the case. But DI Matt Brindle is out of action. He was badly injured and his sergeant was killed in a criminal ambush. He is drawn into the investigation and must decide whether he wants to go to back to his old life.

What is the real connection between the victims … and who will be next?
