Nobody ever knew what happened to the Brindleys. One summer they were there - flashy, loud and beautiful - and then they were gone. A mother, father and two children, vanished into the East Anglian night. Some said the family never made it home from the party; their speeding car thrown off the tracks and the four of them silently buried in the marshes. Others said they had simply moved on. For 30 years, the case remained as cold as the freezing waterways of the Norfolk broads. Until Cam Killick found the car. An ex-marine and ex-SBS officer, Cam Killick's PTSD has made the return to civilian life a living nightmare. As a cold case diver it is his job to scour the waterways of the country for the lost, the submerged, the drowned, laying their stories to rest alongside them. Except when Cam throws open the doors to the Brindley car, all four bodies are missing.
