"But bacon's not the only thing That's cured by hanging from a string." And they did hang Gary Malachi - in1964 for the murder of two school-girls. But was he guilty, or had he been framed by wicked and malicious police officers? In his latest case, recently promoted Detective Superintendent Michael Gregory is baffled by the deaths of Charles ("Charlie Artful") Barrett and Gregory's old friend, solicitors' managing clerk Sid Burton. Both former murder squad detectives, Barrett and Burton investigated the murders of Amy Boniface and Laura Smith in Plymouth in 1964, finally arresting and charging Gary Malachi with both crimes - for which he was subsequently hanged. As Gregory's investigation progresses, it becomes clear that some person closely connected to Malachi is convinced that he was framed and is seeking to avenge his death. As he places the original killings in Plymouth under a microscope, Gregory slowly uncovers the awful truth of what took place a half-century before, at the same time discovering who killed "Charlie Artful" and Sidney Burton. This is fifth of the much-acclaimed Michael Gregory novels and reviews of all of them can be seen at Amazon.
