Personal grief has to be put aside when brilliant detective Red Metcalfe is faced with a series of grisly and sadistic killings. Each body provides a taunting clue to the murder method to come and the police team and their families could be next on the hit list.

DCI Charlie MacIntyre has paid a terrible price for putting the wrong man behind bars - and he won't be the last. Now the stakes are raised for Red to track down the sadistic murderer whose aim is to be judge, jury and executioner of the guilty. But the killer is always one step ahead.
