Jigsaw is a 1962 British black and white crime film written and directed by Val Guest and starring Jack Warner and Ronald Lewis. It is based on the police procedural novel Sleep Long, My Love by Hillary Waugh, with the setting changed from the fictional small town of Stockford, Connecticut, to Brighton, Sussex, while retaining the names and basic natures of its two police protagonists and most of the other characters. It was filmed with the full cooperation of the Brighton Borough Police, which was under the shadow of a major corruption scandal, and the East Sussex Constabulary.
