The woman gives her name as Betty. No last name. No phone number. Just a meeting place - a deserted, wooded park on the outskirts of Lake Tahoe. The one condition - come alone. San Francisco attorney Kali O'Brien understands client confidentiality, but something about Betty's urgent request has her a little spooked. Whatever secrets the woman is hiding must be very incriminating - and very dangerous. The moment Betty meets with Kali, she's shot and killed by a sniper, and Kali barely escapes with her life. She's left with more questions than answers. Why did the woman go to such lengths to ensure secrecy? And then there's the last thing Betty every said - a cryptic phrase that leads Kali to another unsolved case - the mysterious disappearance of a woman eight years earlier. As Kali get closer to discovering the truth, a killer is right behind her, anticipating her every move, waiting for her to play into his very lethal hands.
