A train hits a snow drift in the frozen Cleveland Hills. In the process of clearing the line a body is discovered, and so begins a dangerous case for struggling Edwardian railway detective, Jim Stringer. Jim''s new investigation takes him to the mighty blast furnaces of Ironopolis, to Fleet Street in the company of a cynical reporter from The Railway Rover, and to a nightmarish spot in the Highlands. Jim''s faltering career in the railway police hangs on whether he can solve the murder - but before long the pursuer becomes the pursued, and Jim finds himself fighting not just for his job, but for his very life as well.
