Love from a Stranger (1947)

Cecily Harrington, struggling along on a small allowance, wins a fortune in a lottery. She decides to travel rather than marrying her fiance Nigel Lawrence. A stranger, Manuel Cortez, comes to rent her flat and she falls in love with him, and they are married. For their honeymoon, they go to an isolated English college where she, unlike the audience, doesn't realize she has married a fortune-hunting Bluebeard with a few murdered wives in his past. The question is will she be able to repent in leisure her decision to marry in haste.
