Seen as a late night movie on TV in the 1960’s, probably made in the 1950’s but maybe 1940’s, film noir, gothic type. black and white. Spooky house type. English. I don’t think there were any major actors. Plot line: Story mostly at night, at or near a spooky out-of-the-way house, a man apparently commits suicide by jumping off a high cliff onto rocks and ocean below; witnessed by one of the movie characters. But then strange things occur in the house. It turns out the man had rigged a secret net on poles which swept him underneath the cliff onto a ledge when he pretended his suicide. I recall only this dramatic deception shown at the movie’s end.
