Edge by Jeffery Deaver
About: Henry Loving, "a lifter," specializes in extracting information from human targets by any means necessary (i.e., torture). Corte, "a shepherd," is an agent in the Strategic Protection Department of a secret government agency normally assigned to protect high-profile targets. An intercepted communication identifies Loving as the lifter ordered to target Ryan Kessler, a Washington, D.C., metro detective. While Corte attempts to protect Kessler's family and identify the "primary," Loving's employer, Loving seeks the edge to get the information he needs to extract. Corte, a board game aficionado and game theory student, and Loving are well matched, sharing a history that ups the stakes and makes the contest personal. Deaver's first first-person narrator, Corte, is an exciting new weapon in the author's arsenal of memorable characters. (from amazon.com)
I love thrillers, and this one seems like a brain teaser. Its been awhile since I've been able to find/read a good thriller but this one might just be it! I wonder if the library has a copy.
