An old journalist friend of Perez's, Jerry, dies in a suspicious car accident. However Jerry had been away from the Shetland's for a while so his motives for coming back are unclear. Perez suspects his ex partner Evie may have been involved and she is about to get remarried.
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.
