Naples, 1931. A bitter wind stalks the city streets, and murder lies at its chilled heart. When Maestro Vezzi, one of the world's greatest tenors, is found brutally murdered in his dressing room at Naples' famous San Carlo theater, the enigmatic and aloof Commissario Ricciardi is called to investigate. Arrogant and bad-tempered, Vezzi was hated by many. But with the livelihoods of the opera at stake, who would have committed such a callous act?

Was the biggest case of his career the worst mistake he ever made? Ten years ago, DCI Jack Logan stopped the serial child-killer dubbed "Mister Whisper", earning himself a commendation, a drinking problem, and a broken marriage in the process...When another child disappears a hundred miles north in the Highlands, Jack is sent to lead the investigation and bring the boy home. But as similarities between the two cases grow, could it be that Jack caught the wrong man all those years ago?

When Harold Merefield returned home in the early hours of a winter morning from a festive little party at that popular nightclub, the Naxos, he was startled by a gruesome discovery. On his bed was a corpse. There was nothing to show the identity of the dead man or the cause of his death. At the inquest, the jury found a verdict of ‘death from natural causes’ - perhaps they were right, but yet? 

They’ve made a fresh start at the Pizzofalcone precinct of Naples. They fired every member of the investigative branch after they were found guilty of corruption. Now, there’s a group of detectives, a new commissario, and a new superintendent. The new cops immediately find themselves investigating a high-profile murder that has the whole town on edge.

Detective Sergeant Chris Waters got the call at 05.29 that July morning. This is it, said DCI Reeve, you'll be first there, it's all yours, you're the crime scene manager. Suddenly, after months of waiting and wondering, Waters finds himself in at the deep end, and alone at the scene of a puzzling murder. As the investigation proceeds, the detectives at Kings Lake Central find themselves visiting familiar places and talking to some familiar faces, while old enmities reappear in the incident room. Before this is over, Chris Waters will need to make a career-changing decision.
