A servant often brings her young son to work. The problem is that the husband who pays her', Mr. Raydon, demands the child NOT be there. Later, when the housekeeper brings the child to work and the kid accidentally breaks something, the man is angry and fires the lady. In retaliation, she poisons him. However, the wife is blamed for this by her vengeful mother-in-law and soon the widow stands trial for his murder.
I found it very odd that Mr. Raydon was killed immediately after firing the housekeeper and before she actually left the Raydon home....and the District Attorney's office didn't assume the housekeeper was the murderer. Certainly she had an obvious motive...plus she actually DID kill the man. This is a shortcoming of the episode as the best 'evidence' they seemed to have against the wife is that her meddlesome mother-in-law hated her and assumed the worst. And, much of the old woman's testimony seemed inadmissible...opinions and hatred but no real evidence. And, the stories the old woman recounts on the witness stand all seem ridiculous and hard to believe. As a result, the episode seemed very weak...extremely weak in fact. And, because of that, it all seemed irregular and highly improbable.
In some ways, "What Really Happened" is a variation on Akira Kurosawa's "Roshomon"...where different folks recount the same story...and recount it VERY differently. But "Roshomon" is a brilliant film...a real groundbreaker...and this episode of "The Alfred Hitchcock Hour" just isn't. The twist towards the end was interesting...but otherwise everything about the court scenes seemed flimsy.
Overall, not especially logical...and a very weak episode from start to finish.
