Shadow of a Doubt
Dennehy’s expert direction springs the trap quite effectively, because that is the most amusing way to operate in this case.
A lawyer on the bottle gets a call from the old flame, her husband is dead, her stepdaughter accused of murder. The cops have a videotaped confession browbeaten out of the girl or not, she was confined at home or abused, or not.
Actually, Mom and the girl are in love and now free to live on the old man’s money.
The lawyer goes home, contemplates his wayward daughter with a kindlier eye.
