A body is found on a beach in North Devon. DI Matthew Venn and his team search for a way into a case that has no witnesses, no forensics and no motive.
Matthew and the team continue to hunt for clues about the victim and theorise who might have a motive to murder. Connections are made between the victim and the Brethren community.
The prospect of rebuilding a relationship with his mother blurs Matthew's ability to focus on the case. Lucy and Gaby can no longer stay quiet amid shocking revelations.
Despite key breakthroughs, the team are frustrated until an important piece of evidence sets Matthew on the path to finding the murderer.
