Movie Review: ***^The Lady Vanishes (1938)

***The Lady Vanishes 1938 is an old Alfred Hitchcock.  It's a  spy story, but you don't realize this until almost the end of the show.  What you do know is that a woman has vanished, and her new acquaintance is looking for her.  However everyone else on the train tells her there is no such person.  The young lady is accused of being psycho as everyone tells her the other person does not exist.  However, the young woman looking for her gains an ally, and together they not only avoid people after them, but also eventually figure out what is gong on.
