For Detective Chief Inspector Joe Mottram, a summer on the island of Capri was meant to be an opportunity to reconnect with his troubled teenage daughter, Angelica, and his Italian in-laws, after his wife's Francesca's death by a hit-and-run.

But when a British tourist is found dead and a member of his late wife's family is accused of murder, Joe is pulled back into a world of police cells, crime scenes and local corruption. As he discovers more about the island, he realises it holds the answers to Francesca's death, which may not have been a tragic accident after all.
