Murder, She Wrote (1984)
1 plot hole in season 2
Revealing mistake: When the first scene at Emma's hideaway was shown, obviously the two characters Emma and Jessica were filmed seperately on the couch and then the film was put together (as both are played by Angela Lansbury). However Jessica did a lot of moving while she was talking, so Emma was looking straight across at where she had been, despite her bending down while she talked.
Trivia: Angela Lansbury is the only actress to appear in all 264 episodes of the show.
Question: Why did Lane Henderson (Louise's father) murder his wife?
Answer: In a flashback scene, it was shown that he had a violent temper, so it stands to reason that he finally killed her in a fit of rage.
