The Mouth of Sheol

What would you do if your husband was a world-renown preacher in an evangelical Christian organization worth millions of dollars, and he killed himself?
No one knows why.
You find yourself in a dilemma where you need to keep his ministry going so that your son would eventually inherit his fortune.
What if you didn't really believe in this born-again movement, and you certainly didn't believe in Jesus. He certainly would not approve of you seducing your own son's best friend.
Yet, you must do everything you can to keep your dead husband's organization going by somehow filling in for him, and at the same time, try to solve the mystery of why he committed suicide.
Can you do all this and still keep your sanity?
