Dr Ethan Winter, Bristol's brilliant but unconventional head forensic pathologist, is called to a chilling crime scene: the frozen body of a young woman discovered in the back of a truck. Leading the investigation are DI Lauren Bell and DS Ellis Daldry, but for Bell, newly arrived in Bristol, working with Winter is an immediate challenge. His effortless charm and confidence leave her deeply unimpressed, and she quickly dismisses him as arrogant and self-absorbed.
