Ex-special investigator Louis Kehlweiler catches sight of something odd on the pavement. A tiny piece of human bone. When he takes his find to the nearest police station, he faces ridicule, but when he recruits 'evangelists' Marc and Mathias to help him, they find themselves facing something much worse. This is a brilliant Three Evangelists novel from France's bestselling crime writer.
