One day Kate Nash was a private investigator. She had a thriving enterprise, a supportive boyfriend, and the perfect business partner. The next day she was arrested for murder. "It's not me. I don't care what you see on the surveillance tape. I was at home asleep."The police showed her the film. She couldn't tell the difference between herself and the woman on the video. She had been a detective long enough to know people spent the rest of their lives in prison on less evidence than the police had on her.She couldn't come up with an explanation for who the person could be or where she came from. When she did found out, it changed her life forever.
