In 1992, Sarah Lingate is found dead below the cliffs of Capri, leaving behind her three-year-old daughter, Helen. Despite suspicions that the old-money Lingates are involved, Sarah´s death is ruled an accident. And every year, the family returns to prove it´s true. But on the thirtieth anniversary of Sarah´s death, the Lingates arrive at the villa to find a surprise waiting for them-the necklace Sarah was wearing the night she died. Haunted by the specter of that night, the legendary Lingate family unity is pushed to a breaking point, and Helen seizes the opportunity. Enlisting the help of Lorna Moreno, a family assistant, the two plot their escape from Helen´s paranoid, insular family. But when Lorna disappears and the investigation into Sarah´s death is reopened, Helen has to confront the fact that everyone who was on Capri thirty years ago remains a suspect-her controlling father, Richard; her rarely lucid aunt, Naomi; her distant uncle, Marcus; and their circle of friends, visitors, and staff. Even Lorna, her closest ally, may not be who she seems. As long-hidden secrets about that night boil to surface, one thing becomes clear: Not everyone will leave the island alive.
