Blake now a detective, is the first CID officer to attend the scene of a murder. Almost identical to one a week earlier. Both young fit men taped into Windsor chairs, mutilated and killed in the same brutal manner. The enquiry gathers pace ranging from derelcit Victorian weving sheds to the heights of Britsh nobility as more victims are discovered and the race to find a potential victim before the killers. Jon Mason's final twist is unparalled.
