This episode started off on such a great premise and then sort of fell apart.
The young woman in this episode is not newly married as the synopsis suggests, they have been married for five years.
And I found it strange that her husband was able to maintain his romantic behavior for that amount of time but as soon as he signs her up for life insurance he is immediately cold and  critical.  Add to that, that the husband after having her freshly signed up for this life insurance then plans to kill her within 24 hours, nothing suspicious about that at all!
And as another poster pointed out she married her husband 3 months after his first wife was killed in their house and new wife is oblivious to any past events.  
And lastly it was odd the way the friend, who was identified at one point in the episode as the husbands cousin, kept pushing her to confront the husband about his previous wife.  the friend/cousin had to have thought the first wife's death was a little odd but yet keeps pushing her to bring it up to the husband.
