Detective inspector Tom Richards from Scotland yard now faces his biggest challenge. Two girls are found dead in Edinburgh.
When their bodies were discovered, the circumstances matched a killer from ten years ago. The problem for Tom is that he had caught the killer for his case. Worse, the alleged killer had been tried, convicted and sentenced to hang. Had Tom made a mistake? Did an innocent man hang?
A miscarriage of justice follows Tom as he tries to solve the case, whilst his personal life turns for the worst, and an old flame comes back into his life.
