Resumen
Keeping watch under the windows of the Paris flat belonging to a politicians nephew, ex-cop Louis Kehlweiler catches sight of something odd on the pavement. A small white object, surrounded by the excrement of local dogs. A piece of bone. Human bone, in fact. Naturally, when Kehlweiler takes his find to the nearest police station, he faces ridicule. But the tiny fragment obsesses him so much that he stops shadowing people with something to hide in the city and follows the trail to the tiny Breton fishing village of Port-Nicolas. Because someone there owns a pit bull terrier. A dog that would take a bite out of anything. Even the foot of a corpse.
