The Ghost Talks (movie, 1929)

Miriam Holt hopes to solve the disappearance of a million dollars in bonds allegedly stolen by her late uncle. A team of crooks is following her, though, in hopes she'll uncover the missing money and they can grab it from her. She checks into a hotel where Franklyn Green works as a desk clerk. Franklyn is learning to be a detective through a correspondence course, and he thinks he's just the guy to help Miriam solve her mystery. The fact that she's a very attractive lady doesn't hurt, either.
