A wedding day turns into a far darker affair in the idyllic Lake District.

On a glorious July morning in the pretty Lake District village of Threlkeld, Simmy Brown and Christopher Henderson celebrate their wedding day. While the event passes off without undue calamity, when most of the guests have departed a severely injured young man is found nearby.

Pressure on police resources compromises the investigation and speculation is rife. Was it an accident or something more sinister? What was just a chilling suspicion develops into an altogether more disturbing theory.
