“More in a Hitchcockian mood, even more legitimately since the script is by Sidney Gilliat. A colorful and intriguing mystery dealing with the search for a Mystery Man head of an international organisation who contrives to kill off enemies by getting them on to trains - and then, with cavalier disregard for other passengers, wrecking the trains! A snappy, light-hearted thriller, directed by Albert de Courville and starring Edmund Lowe and Constance Cummings.”
