October 1952: England's worst train crash stuns Britain.

112 people were killed and 340 injured when the sleeping-car express from Perth ploughed into the London bound commuter service standing at Harrow & Wealdstone station. Within seconds, a northbound express smashed into the wreckage.
The Ministry of Transport's investigation into the crash posthumously blamed the experienced crew of the Perth express. But why several danger signals were passed remains unanswered. What went so dreadfully wrong on the footplate of the Perth express?
Lorna survived the carnage, but seven years on she still suffers terrible nightmares and daytime traumas. She hopes DI Crosier, of Crewe's Railway Police, will know something to help her come to terms with her terrors and the tragic loss of her sister, brother and niece.
Crosier's investigation of British Railways' first serial killer, leads him to suspect that he is linked to the Harrow and Wealdstone crash.
His daughter is targeted by the killer, and his wife's refusal to move to Crewe, only add to Crosier's problems, and his love life.
