A luxury yacht arrives in Reykjavik harbour with nobody on board. What has happened to the crew, and to the family who were on board when it left Lisbon?
Thora Gudmundsdottir is hired by the young father's parents to investigate, and is soon drawn deeper into the mystery. What should she make of the rumours saying that the vessel was cursed, especially given that when she boards the yacht she thinks she sees one of the missing twins? Where is Karitas, the glamorous young wife of the yacht's former owner? And whose is the body that has washed up further along the shore?
