Who can say no to a vulnerable woman who needs assistance? Certainly not Patrick Miles Atwater. But it may be the worst mistake he will ever make.

Patrick, a private investigator, is a hero in Los Angeles. An ex-marine and ex-police officer, he’s truly a stand-up guy. His duty, as he sees it, is to help the victims of monstrous men-and he takes that obligation seriously.

When Rachel Stone Barbieri finds him at his local watering hole, she says she needs his help-but her motives are murky and her intentions unclear. Patrick knows he can’t trust her, but at the same time, he finds he can’t turn this intriguing woman away. Claiming she suspects her husband of having an affair, she wants to engage Patrick’s services to confirm her suspicions-and despite his better judgment, Patrick takes the case.

He was wary of her from the get-go, but even Patrick can’t foresee the magnitude of trouble this simple case of adultery will lead to. Accused of murder and hunted by the police, will Los Angeles’s hero uncover the truth and live another day-or will the woman in the yellow dress be his ultimate downfall?
