Walt Duffy spent his life traveling the world, documenting the beauty and wonder of nature through the lens of a camera. But there was nothing natural about the ugly way he died, his skull fractured by an unknown assailant, his broken body left sprawled right in his own backyard. The irony wasn't lost on Boston attorney Brady Coyne. He first met Duffy while handling his divorce a decade earlier, and their relationship evolved into a working friendship. He knew Duffy well, or so Brady thought. That belief is about to be put to the test when Coyne is brought in for questioning by both the local police and the FBI, who reveal Duffy's ties to a notorious ecoterrorist group that is currently setting fires to homes and offices around the Boston area. And when Brady begins to get mysterious calls in the middle of the night, warning of the next fire to be set, he knows that he has become an unwilling pawn in a chess game with the deadliest of consequences.
