Hiding in Plain Sight

This book starts out with a bang, or a flame, and we learn right away who the arsonist is in a rural Virginia firebug spree. That worried me. I assumed that without the mystery of discovery, I would be unmotivated to continue. Wrong-oh. Somehow, the author manages to keep things at a thriller pace, through the myriad and proverbial stones that were definitely turned, the multiple clues tracked unsuccessfully, and the countless dead ends. Gripping, sad, mystifying--should be a movie.
