The harsh summer in Shetland began with tragedy. Joseph, the adult son of former Marine Ray Campion, died in the rough seas. The poor father is inconsolable: he had high hopes for the young man... In order to survive the grief alone and not listen to the residents of a small fishing village discussing the event, the veteran goes on duty at the lighthouse. When sympathetic neighbors decide to treat Ray to fruit and support him in difficult times, they find him sitting on the floor with... a three-foot harpoon in his neck. Who of those living on the island is capable of this? There are practically no strangers here. Only a person from his inner circle could kill Campion. Eighteen-year-old Adam, who came to the island to visit his grandfather, thinks the same. The guy is shocked by this terrible event and decides to solve the crime before the police. The island is frozen in anticipation of the denouement... A novel in the best traditions of the classic English detective story. A brutal crime on a remote fishing island, a narrow circle of suspects, an insightful young detective, an unpredictable psychological ending to the story... And all this under the sound of the stormy cold northern sea...
