An express train rushing toward the north of England; a group of exceedingly mysterious characters; suspicious happenings in rapid succession; a humorous yokel; a bicycle accident; a lady in distress; and after much mystery a satisfactory conclusion, making this Farjeon story one of the best of its kind. Young Freddy Reeve wants an adventure, but may get more than he bargained for when he encounters the lovely Miss Lydia Leveridge, who provokes more questions than she answers. Freddy finds himself questioning the actions of various fellow passengers, but is quickly thrust into the wake of a criminal plot. He jumps at the chance to save the girl, which brings even more trouble than he imagined. The fast-paced plot leads to a dangerous climax, where several lives are on the line. The 5.18 Mystery was first published in 1929.

Richard Temperley arrives at Euston station early on a fogbound London morning. He takes refuge in a nearby hotel, along with a disagreeable fellow passenger, who had snored his way through the train journey. But within minutes the other man has snored for the last time-he has been shot dead while sleeping in an armchair. Temperley has a brief encounter with a beautiful young woman, but she flees the scene. When the police arrive, Detective Inspector James discovers a token at the crime scene: a small piece of enamelled metal. Its colour was crimson, and it was in the shape of the letter Z. Temperley sets off in pursuit of the mysterious woman from the hotel, and finds himself embroiled in a cross-country chase- by train and taxi - on the tail of a sinister serial killer. This classic novel by the author of the best-selling Mystery in White is a gripping thriller by a neglected master of the genre. J. Jefferson Farjeon (1883-1955) was the author of more than sixty crime and thriller novels that were highly acclaimed in his lifetime. Farjeon is the author of Number Seventeen, a play that was adapted for the big screen by Alfred Hitchcock. His Christmas crime novel, Mystery in White, was republished as a British Library Crime Classic and became a bestseller. Front cover (c) NRM/Pictorial Collection/Science & Society Picture Library
