The Last Innocent Man by Phillip Margolin

Defense attorney David Nash has made a career out of setting monsters free -- and no one does it better. Now a case has come to "The Ice Man" that could help cleanse Nash of the guilt and doubts that torment him: that rarest of all defendants, an innocent man.

A fellow lawyer has been accused of a heinous crime -- the brutal murder of an undercover vice cop. But the case that is supposed to be Nash's redemption could prove to be his downfall, dragging him into a dark and sinister world where lies and the truth are interchangeable; where the manipulator becomes the manipulated; and where every answer spawns more complex and terrifying questions. And as the shadows close in around him, the final question that remains for David Nash concerns his own fate: life ... or death?
