Don't Let Him Kill — John Creasey

A convict has a vendetta against Patrick Dawlish -- and he's just been set free, in this gripping British Golden Age mystery from the Edgar Awardâ€"winning author.
 
Detective Patrick Dawlish has made a lot of enemies putting men behind bars, but none more dangerous than Maurice Gorman, a conman whose son died while being pursued by Dawlish. At his sentencing, Gorman vowed to kill Dawlish and has talked of nothing else for all seven years of his imprisonment -- which has just ended.
 
Immediately, the now-retired Dawlish is besieged by a violent hate campaign starting with mocking phone calls, car bombs, and the abduction of his friend Ted's wife. As events spiral out of control, an even more devastating possibility arises: if Gorman is not behind the attacks, then someone else is. And that person -- hiding behind the ultimate suspect -- may be even harder to stop . . .
