Affair in Darkness

He thought he could keep the other part of his life separate from his home life. His playboy life. A lifestyle he has held onto since he was a teenager. He has everything a man could ask for good looks, power, beautiful wife and kids, and money. A devoted wife, a wife who has put up with his affairs as "it's just what men do."
Over the past eight years he was able to keep his playthings away from his wife and children, making sure to never let any of them get close. It's all about sex and only sex. Once the chase was over, he moved on to the next woman. Now one of them won't go away quietly and could possibly bring everything near and dear to him crashing down. Will he be able to save his marriage and most importantly, not let his private life affect his career.
