When Bampton's coroner, Hubert Shillside, does not return from a trip to Oxford, Master Hugh de Singleton is called. Concerned for his old friend, Hugh takes to the road to investigate. Travel is safer than in times hence but, out of sight of prying eyes, it is still unwise to travel alone.

Hugh finds a body, stabbed and left to rot, but it is not the body he was expecting to find. Indeed, reports of pillage, attacks, and chaos on the roads out of Oxford suddenly seem rampant. Hugh must ascertain whether the incidents are random, or whether something darker is afoot.

The guilty cannot afford to be caught, but what lengths will they go to to cover their tracks, and will Hugh escape unscathed?
