I would like to reread this story.
The husband is working in his home office, when he overhears his son, joking with his friends, that he doesn't know if his dad is his real father.
Husband hires a P.I. gets DNA testing and video of wife cheating.
The revenge is great!
He sues his wife for divorce, her mother for interfering in their marriage, etc.
It was a random story. Any help is appreciated.
