Query: The true story of a pair of drifters who terrorized the D.C. area for 23 days.

What is the face of evil? In this sniper case, the faces are two - a 15-year-old boy and a man old enough to be his father. They are ordinary faces; yet they methodically killed and wounded as many as 5 people a day without mercy. Their movements were random, frustrating police and FBI agents. Acting on mistaken information of a white van, the officials floundered - clueless, while the pair remained invisible and deadly - shooting from a small hole in the truck of a dark blue Caprice. All around them a tempest roared.Authors Horwitz and Ruane tell us chapter by chapter what happened, who the killers were, who the victims were, and how they ultimately were captured.
