The Broken Window (Jeffrey Deaver)

A typically exciting example of the Lincoln Rhyme series, full of Deaver's usual twists and turns. A fiendishly clever serial killer uses the kind of data collected online about each of us not only to track his victims, but to frame others for the crimes. He is only caught after targeting Rhyme's cousin to take the fall for his latest killing. This is as much a warning about issues of cyber-privacy as it is a murder mystery.
