In straight-laced Victorian Britain, the railway line between London and the seaside town of Brighton was a bordello on wheels. Inevitably, the secret trysts and dodgy deals conducted in its curtained carriages led to some unsavoury crimes. A series of murders on the Brighton Line shocked polite society and some remain unsolved to this day. Others saw their perpetrators sent to the gallows. Brighton’s reputation as a Bohemian playground was matched only by the town’s notoriety for violence. The curious characters of Grahame Green’s novel Brighton Rock were typical of those Simon Ford and detective Jacques Morrell encountered on this journey through the archives. The Six O’clock Knock is a Psycho Killer production.
