A killer with a secret message...Little Susan Verity disappeared during the drought of '78. An unprecedented number of police officers went looking for her, but were unsuccessful. Until today. Serial killer Adrian Wicklow was always the first suspect. He has constantly lied to the police about Susan's whereabouts, but this time, he says he will tell the truth. Because Wicklow is dying. When the case is reopened, DS Ian Bradshaw works to find Susan, with journalists Tom Carney and Helen Norton. But this is Wicklow's life's work. Will a killer so easily part with his last secret on the verge of death?
