Fifteen years ago a young British woman was brutally murdered in Mallorca while holidaying with her parents and fiancé. Her killer was never caught, despite a major joint investigation between the British and Spanish police—and the fact that the girl’s mother was one of the Met’s highest-ranking officers at the time. Now, as the anniversary of Katy Pope’s death approaches, the family return to the Spanish island to launch a fresh appeal for information, taking the now skeletal team of Met officers looking into the murder. For DC Maggie Neville, recently seconded to the Met team, it’s her first opportunity to work on an international investigation. But nothing is ever straightforward, and when another girl is found murdered, Maggie and her team have to consider the possibility that Katy’s killer has returned.
