Gilbert is the boy Daubrecq stole from his parents and trained toward the scaffold, and the boy Lupin took on afterward and could not quite save. He is frank, funny, careless with his life, and utterly loyal — he would die at a sign from his master, and the law intends to make him do exactly that. His imprisonment forces Lupin into the open and turns a burglary gone wrong into a race against a fixed execution date.
