The Invisible Ghost

1941. From Google Video:
Bella Lugosi stars in Invisible Ghost as Charles Kessler. Kessler is well thought of by everyone who knows him and when people are murdered on his estate, he is as shocked as anyone else, and when his daughter's boyfriend is accused of murder he tries his utmost to help the young man. There is another side to Charles Kessler though. A side that he is not even aware of himself.
