"A mysterious murder on a flying express train, a wily Italian, a charming woman caught in the meshes of circumstantial evidence, a chivalrous Englishman, and a police force with a keen nose for the wrong clue, are the ingredients from which Major Griffiths has concocted a clever, up-to-date detective story. The book is bright and spirited, with rapid action, and consistent development which brings the story to a logical and dramatic ending."
