The Flying Scotsman, one of the world's legendary train journeys, has many attractions for Edward "Mitch" Mitchell, from the obliging porter to the mean guard to a troop of rough-and-ready soldiers in easily lifted kilts in the third-class carriage. But Mitch may not have time for them all before they arrive in London. When the train gets stuck in a tunnel, a dead body is found in the first-class toilet! Ever-ready Mitch decides to intervene and solve the crime. With his new Belgian sidekick Benoit, he pursues the killer through a crazy kaleidoscope of movie stars, drug dealers, royal scandals, and queens of every description. Can he finger the villain before the villain fingers him? What is the connection between Buckingham Palace and a bunch of backstreet pornographers? And what is the mystery of the secret tunnel? Mitch intends to go all the way to figure it all out.
