Three hundred and fifty thousand francs vanish from a banker's safe overnight, and only two men had the key — the banker and his cashier. Gaboriau was a cavalry trooper and a lawyer's clerk before he invented Monsieur Lecoq; this is the case where Lecoq works from the scratch on a lock plate, and the reading of that scratch is the heart of the book.
