Sherlock Holmes is engaged to protect a valuable diamond aboard a train traveling from London to Edinburgh, but when the gem disappears and its owner is murdered, Holmes suspects an old foe.
One of the final pairings of Rathbone and Bruce as Holmes and Watson, and despite the film's low budget, there's some entertaining mystery and suspense in sort of a small-scale version of Agatha Christie's "Murder On The Orient Express." Though a good portion of the film is devoted to Watson's errors in trying to question the suspects, Rathbone still is given plenty of opportunity to shine, and Neill makes the most of some stock footage in convincing us the game's afoot on a speeding train.
