One night, in a private boarding house in Scarborough, a railwayman vanishes, leaving his belongings behind. A reluctant Jim Stringer is sent to investigate. It is March 1914, and Jim Stringer, railway detective, is uneasy about his next assignment.
When his train is nearly derailed, a young Yorkshire railwayman once more turns sleuth. Since his previous escapade (The Necropolis Railway, 2007), engine cleaner Jim Stringer has gotten closer to his lifelong dream of driving a train. As fireman aboard The Blackpool Highflyer, he gets to ride alongside rugged driver Clive Carter.
