Near St. Brynneys in the Welsh border country, isolated by heavy snow and flooding from the thaw, a calamity has occurred. Old Dr. Robinson, a known 'menace on the roads', has met his end in a collision with a jeep on a hazardous junction. But when the police arrive at the scene, a burning question hints at something murkier than mere accident: why was there a second body--a man not recognised by any locals--in the back of Robinson's car?

As the local inspectors dive into the muddy waters of this strange crime, Chief Inspector Julian Rivers and Inspector Lancing are summoned from Scotland Yard to the windswept wilds, where danger and deceit lie in wait.

Puzzling and atmospheric, this exceedingly rare mystery from one of the masters of crime fiction's Golden Age returns to print for the first time since its publication in 1954.
