This is the final book in the Detective Markham mini series.
A body is found and it turns out to be the body of a doctor who disappeared from a Mental Hospital a year earlier. It was assumed the disappearance was the result of depression and that he had made a new life elsewhere or committed suicide. Tests reveal neither of these was the case and he was in fact murdered.
Markham is tasked with investigating that and also a 'secret' investigation involving corruption. As is usual when Markham is around more bodies turn up and the team is up against time to crack the case before more people lose their lives.
A steadily moving detective series that keeps the readers' interest as we follow the investigation around the twists, turns and lies all the way to the surprising ending.
