Brigade Criminelle is mobilised when a fatal stabbing, an anticipated delivery of lethal drugs from Marseilles, and the discovery of a thirty-year-old corpse in an ancient turreted tower in the
town of Puyceldome coincide with a frantic search for two murderous hitchhikers, all on Chief Inspector Pel's patch. And as folk-dancers, stilt-walkers, fire-eaters, and jugglers lurch through
a night of carnival, Pel stalks his prey.
