Washington's water supply has been contaminated, and the President's son and daughter have been kidnapped. Despite the fact that some pretty influential people want to exclude him, Alex Cross finds himself involved in both investigations.
The question is, are theses two events related? Regardless, time is running out for both. Alex must try to find the President's children, while preventing another attack in the nation's capital.
Two stories are told simultaneously, resulting in a "can't put it down" thriller. One of Patterson's better Alex Cross stories.
