Proof Positive

New York Times bestselling author Phillip Margolin returns with a shocking and enthralling thriller about the way CSI evidence can be misused by a killer with his own twisted sense of justice.

doug Weaver is a defense attorney who believes the best of his clients, and Jacob Cohen, on trial for murder, is no exception. Yet Bernard Cashman, a forensic expert at the Oregon State Crime Lab, finds evidence that indisputably connects Cohen with the crime.

Frustrated and confused, Doug consults Amanda Jaffe, star of Margolin's spine-tingler Wild Justice. Amanda and her father, Frank, are working on a case that seems completely unrelated: gangster Art Prochaska is accused of murdering an informer. When Amanda starts looking too closely at the seemingly air-tight evidence in these two apparently unconnected cases, people start to die -- and she discovers that a madman with the power to alter the truth is on the loose.

Phillip Margolin has written nineteen novels, many of them New York Times bestsellers, including his latest novels Woman with a Gun, Worthy Brown’s Daughter, Sleight of Hand, and the Washington trilogy. Each displays a unique, compelling insider’s view of criminal behavior, which comes from his long background as a criminal defense attorney who has handled thirty murder cases. Winner of the Distinguished Northwest Writer Award, he lives in Portland, Oregon.
