Newsreader Devon Bliss was murdered in the prime of her life, and the police and tabloid press are convinced that loner Graham Scobie is guilty. The eminent defense lawyer Sir John Hathaway persuades the court that the evidence is circumstantial and Scobie walks away a free man. When Hathaway becomes the target of vandalism and threats in his retirement, Superintendent Gregory Summers is called in to investigate. Graham Scobie has recently moved to the area, but why should he threaten the man who saved him from prison - and why is tabloid journalist Reuben ap Morgan suddenly sniffing around?
