Death Wore White by Jim Kelly

A blizzard strands eight cars on a lonely coastal road. When one of the drivers is discovered dead--a chisel through his eye--the detectives are stymied. None of the drivers has seen anything suspicious, and there are no footprints leading to or from the vehicle.

Detective Inspector Peter Shaw, recently promoted and now paired with his father's former partner, has not only got the murder to solve, but a body has washed up on the beach, with a suspicious bite mark. And Shaw wants to re-open the case of a child murder that caused his father to leave the force in disgrace.

Lots of suspects and red herrings. Fans of British police procedurals will want to give this author a try.
