***SPOILERS*** With their marriage on shaky ground to begin with it was when a half drunk Felichy Sampson, Dee Hartford, blurted out the fact that she was leaving her husband Paul, Berry Sulliavn, for another man,it could have been worse if it was a woman, that he just flipped out. Striking Felichy in a wild rage she fell off the boat that they were sailing on with their friends and drowning! This all happened out of sight of those below deck who were drinking and playing cards. With Felichy reported missing it's assumed by the local Sheriff Jordan, Claude Akins, that she lost her footing and fell to her death off the boat.
It's in fact Paul who later feels that he has to pay the price for Felichy's death even though no one accuses or even suspects him of it. What's even more strange is the by now totally out of his skull and paranoid Paul want's to find who this other man, the person that Falichy was to dump him for, is and do a number,or murder, him as well! Despite trying to get himself arrested for Felichy's death no one not even Sheriff Jordan believes Paul. They think he's nuts and guilt ridden over her death and wants to pay for it even if it leads him straight to the electric chair. Which in fact was not 1st degree murder but an accident on homicide.
***SPOILERS*** In the end Paul does find out who this other man in Felichy's life is who in fact provided him with an alibi back when he tried to prove his innocence in her death. With him being seen to be insane or suffering from a serious guilt complex Paul is committed to a local sanitarium until he can get, if he ever can, his head together. Risisting to the very end and claiming that he in fact did kill his wife Felichy Paul is taken away by the the sanitarium workers or men in the "White Suites" as the episode ends. That's until, according to Alfred Hitchock's epilogue, he's finally believed and convicted of the crime , 1st degree murder, that he claims and given his wish of joining Felichy in the world beyond!
