Steve Gibbs was what was generally called 'A Fixer.' If you wanted something sorted out he was the man who people called in. He was good at his job, being discreet yet successful, was well respected by his clients and proficient in getting the required results. When his wife became ill after a car accident he gave everything up and vowed never to go back to that way of living but after her death found it hard to find anything to stimulate him so when an unexpected visitor called with a request for his help he decided to do one more job: - that way he would know where his future lay. After seven years he returns to London to find out if William Booth, a noted criminal psychologist, really died as a result of a car accident as his widow had recently received an anonymous letter stating otherwise. As he delves deeper into the circumstances surrounding the accident Gibbs uncovers information that connects it with two other deaths of retired experts who Booth had worked with on a case of triple homicides fifteen years previously. When the name of George Plant crops up it appears that the old case the three deceased had been heavily involved in was about to be re-opened and it soon becomes clear that somebody is trying to prevent it from happening. A shocking revelation for Gibbs is that information comes his way that incontrovertibly links his wife's death with his investigations.
