Night Without Stars [1951] [DVD]

David Farrar is virtually blind and retires to the Riviera where he falls in love with Nadia Gray. Then he tangles with murderers, forgers and blackmailers when he discovers she is the widow of a resistance fighter.

He's pushed off a cliff which forces him to get his sight restored and, very smart this, return to the Riviera still claiming to be blind so that he can trap the dirty rotters. Winston Graham adapted his own novel for this unassuming, enjoyable little thriller.
