I regret to say that this is one of the episodes of "The Hitchcock Hour" that really makes you wonder whether Hitch was losing his grip... Of course, it's not easy to provide the TV audience with a thriller every week, and so it's only logical that not ALL of them can be great. But this one can actually only be described as a pretty weak effort to imitate great classic Noirs like "The Two Mrs. Carrolls", or to a lesser extent, "Conflict"...
The well-known story of an initially unsuspecting new wife (she'd got to know her husband through a marriage institute, and only gets to see him the first time the day he picks her up in her new 'hometown', and they go straight to the justice of the peace to get married). His home doesn't please her at all, it's a cold, dark shack poorly furnished (the only thing that provides something of an eerie atmosphere); and what's worse, she soon finds out from the gossip of the local women that her new husband has been married before - and his wife had died after only six months of marriage from a strange food poisoning... And so, as she perceives everything he's planning to do with her as well, she becomes alert and buys a gun (without a gun license??), so that he won't be able to take her by surprise...
Now, I hate to write negative comments about movies or TV episodes - but in this case, I really can only say that even after half of the running time, I was already waiting for the end... Not out of curiosity, although I WAS hoping for one of Hitch's typical sudden plot twists (which never occurred), but because I was simply bored - and except for that, those housewives of the 60s, as they are portrayed here, must have been even worse than those of the 50s! No wonder that the 'generation of '68' rebelled against their parents...
You can certainly find a LOT of great, suspensive, chilling episodes in "The Hitchcock Hour" - but THIS one IMHO ISN'T one of them.
