Susan Carter needs to find a man. Not just any man, but the stranger who fathered her unborn child. In desperation, she turns to David Knight, one of the detectives working for White Knight Investigations. She's sure she'll look bad to David -- she doesn't even know the last name of the man she's searching for -- but she has no choice. It's the only way to find out about her child's father. David Knight doesn't expect to like every client he has. What surprises him is how much he likes Susan, especially since he knows she's keeping things from him. If she wasn't, wouldn't she tell him about the man who gave her the ring she wears on her left hand?
