San Francisco defense attorney Kali O'Brien’s newest case is casting doubt on the one principle she cherishes most—the absolute dead certainty that her client is telling the truth. Grady Barrett, a wealthy computer magnate married to Kali's best friend, has been arraigned in the rape of Deirdre McPhearson, a Bay Area single mother. Despite his pleas of innocence, Kali’s instinct tells her that Barrett may be as guilty as sin. Then Deirdre plunges to her death from a second-story balcony. A tragic accident? Or cold-blooded murder? Now, bound to a client she is afraid to trust, Kali soon finds her own life in jeopardy unless she can outwit a murderer who’s determined to win in this diabolical game…at any cost.
