Duck, Duck, Goose

On a wet and miserable September morning, DI Stephanie Broadbent is called to a shocking crime scene. A man has been discovered in local woodland — naked, covered in goose fat, wrapped in goose feathers, his mouth stuffed with them.

What appears to be a bizarre crime scene becomes more concerning still when duck heads start appearing through people's letterboxes.

It soon becomes clear that the incidents are related, and that the killer is playing a sordid real-life game of Duck, Duck, Goose — but can Stephanie and the team catch them before they complete another lap of the circle?
