"The Man Who Watched Trains Go By" with Claude Rains (1951)

Claude Raines plays a man who has been the head clerk/bookkeeper for 18 years at a firm in Holland. He lives by the sound of the train whistling to and from Paris his whole life, while he remains where he is.

A scandal at a rival firm leaves that firm bankrupt. But, though it has been proven the bookkeeper was innocent of any wrongdoing or knowledge of the crime by his boss, his life and career are ruined anyway. Even Claude cannot help him find a job.

Through a set of circumstances a police detective arrives from Paris tracing some Dutch currency which has been circulating in Paris on the black market. He comes to Claude's firm. The boss is most cooperative. Too cooperative.

Out walking one night, Claude finds his boss burning the books and running away with the firm's money. They struggle and the boss falls in the canal and drowns. The firm's money is strewn on the ground where it fell, along with a train ticket to Paris. What should he do about that? There are no more books, but keeping the money will make him guilty of embezzlement.  And leaving his family behind is not an option he really cares for. But this is an extraordinary situation.

What should he do? Tell the authorities the truth and risk disbelief and ruin? Or is there another way? And does that train whistle to Paris have an influence? Who can say?

Will he go to Paris so that it looks like his boss stole the money? Is it morally okay? After all, the boss was going to leave him holding the bag.....

Wonderfully adapted from the novel, and filmed in beautiful, almost muted color. This 1952 film stands the test. Also released as "The Paris Express".
