Schneider. Cheerful, friendly, affluent Schneider with his innocent passion for model soldiers. Callan hunts again And again his tool is Lonely, the most frightened little man in the underworld.
It is Lonely who gets him the gun, a Noguchi Magnum 38 calibre. A magnum for Schneider. The operation is studded with leathal booby-traps, but Callan's own inhibitions are the most dangerous.” DRIVE
