In fog-shrouded Victorian London, a ruthless serial killer is on the loose.
Autumn, 1888. While the populace is horrified by Jack the Ripper’s murder spree, another, less publicized killer is at large.
Tucked away on the inner pages of daily press, a few articles tell of the strange murders on board the carriages of the London Metropolitan Railway. Each murder takes place right after the Ripper killings, as the murderer appears to be taking advantage of the lack of police resources to tackle two major investigations simultaneously.
Inspector Albert Norris is charged with bringing the railway killer to justice, but clues are few and the killer’s motive unclear. Norris has to carry out his investigation ‘quietly and without causing a public panic’, as the authorities try to maintain confidence in the railway system’s safety.
The press knows even less, and Norris can count on little help from above as he attempts to solve the inexplicable series of murders.
