Troy is partnered with beautiful, ex-model Angela Becker, a superb undercover cop in her own right. The two of them quickly find that they are on the trail of something far larger and darker that what Troy and Rockett had initially assumed: an ongoing international conspiracy that has spanned not only decades but generations as well.

Proof Positive takes the reader from rural Vermont to the swampland of Florida and into the mountains along the Austrian-Italian border, as Troy and Becker hunt for the truth about one girl's past and the history of an entire nation.
