I won't spoil the ending, other than to say that until I got there I was pretty tired of this episode. Hitchcock's portrayal of shrew-like women is pretty consistent and this is no exception. History has shown us that he was a bit of a misogynist, especially in his movies (Marnie, The Birds, etc.). The long suffering husband has been portrayed ad- infinitum. As I've tried to catch up on these episodes, I've run across so many abused men. Most recently it was the man who murdered his wife and locked her in the trunk of his car, only to be foiled by a highway patrolman. Anyway, this one is so self centered that she can't see what a nice life she has. She is enamored with some film star and truly believes that they are alike in appearance and talent. When she strikes, we know the wrong person has paid the price. Enjoy this one. It has a payoff.
