Leonard Lawson was a respected professor of medieval art. He lived a quiet life in a suburb of Liverpool with his grown-up daughter. As far as anyone knew, he had no enemies. Louise Lawson watched her father die. Before she blacked out, she saw his body mutilated and deformed, twisted into a hellish parody of the artworks he loved. Investigating a killer bringing medieval horror to Merseyside, DCI Eve Clay must overcome her own demons to unpick the dark symbolism of the crime scene. A 50-year silence has been broken—with a message written in blood.
