Sale, Greater Manchester, July 2012.
Robert and Patricia Seddon, sixty-eight and sixty-five, married for forty-seven years, are found shot dead in their home on Clough Avenue. A shotgun lies across Robert's lap, and the scene tells a simple, dreadful story of murder and suicide.
It is a lie. Four months earlier, a hired BMW carrying the couple and their grandson had plunged into the Bridgewater Canal, and the man who climbed clear, then posed as a hero on the sinking roof, was the same man who stood to inherit everything: their son.
This is the story of Stephen Seddon, of the parents who gave him money, houses and unconditional loyalty, of the father who worked out the truth and confided it to his doctor the day before he was murdered, and of the trial that ended with a life sentence and a minimum term of forty years.
