The Passenger From Scotland Yard

> Five men sat in a railroad compartment on the mail train from London to Dover, sharing the discomfort and amenities of a train ride in the 1880s. The same five men boarded the Channel steamer and crossed to Calais where they entrained for Paris. When the train reached Paris, however, it was revealed that one man was a detective from Scotland Yard, on the trail of a fortune in stolen gems; one man (identity unknown) was a murderer; and another was a corpse!
