The discovery of seven-year-old Catriona's body after almost two decades prompts Jimmy Perez to take Magnus in for further questioning. But at the station, the recluse's distress ends in him in attacking the inspector, and he is sent for a psychological evaluation. Ploughing on, Perez re-examines the evidence, but it is only when Catriona's brother reveals she had a secret hiding place at their old home - the same house where Catherine also lived - that he finally sees a glimmer of hope.
When a young archaeologist discovers a set of human remains, the Shetland community is intrigued to know if it's an ancient find or a contemporary mystery. And when an elderly woman is shot on her land in a tragic accident, Perez and his team find themselves at the centre of two feuding families whose envy, greed and bitterness has divided the surrounding community.
