This is the first Percy Peach novel, or at least the first featuring DS Blake. It sets the tone and conventions for the novels to follow: Peach joins the North Lancashire golf club, heaps scorn and mockery on his boss Tommy Tucker, is assigned a murder investigation in which the body has been found 2 years after the fact, and brings the investigation to a successful conclusion despite the lack of physical and forensic evidence. In this case there was essentially no evidence against the perpetrator, so Gregson had to invent a Perry Mason-like ending in which the accused simply confesses after being confronted with the suspicions against him.
