Winter, 1980. The Yorkshire Ripper has just claimed his thirteenth victim. Ripper thirteen, police nil. As public anger against the police mounts, Assistant Chief Constable Peter Hunter is sent to take over the investigation. The Strafford Shootings remain unsolved, & the murders of the Jubilee summer of 1977 are still attributed to the Ripper. But Hunter soon realises that all is not as it seems
- & that the police are more heavily implicated in the killings than anyone could have imagined. Jack Whitehead, alone & mad in a mental institution after trying to exorcise the demons from his head with hammer & nail, appears to hold the key. What is the connection between the Ripper & this fresh spate of violence? & what will happen when these men's separate hells collide?
