The police chase a speeding car through the streets of Helsingborg. When they reach the quay, the driver keeps going, straight into the cold, dark waters of the Oresund strait. The body recovered from the wreck is that of Peter Brise, one of the city's richest tech entrepreneurs. Fabian Risk and his team are confident this is suicide. Young, rich, successsful - Brise just didn't know how to ask for help. But then the autopsy reveals something unexpected. Brise was already dead when his car crashed. He'd been brutally murdered two months ago. His body frozen in perfect condition, at 18 degrees below zero.
