"You don't want to miss this captivating new series!" Tess Gerritsen, New York Times Bestselling Author of the Rizzoli & Isles series. THEY SEE WHAT NO ONE ELSE SEES Every crime scene has a smell. A look. A trail of DNA. It also has a feel. An emotional residue that lingers... floating unseen, like bacteria in the air, just waiting to be absorbed. To be experienced.To be interpreted. And only the man, the woman, and the boy know this. He's called the Harbinger, a serial killer using Georgia and Florida as his hunting and dumping ground. But when he sends a letter to the federal/state task force that has assembled to find him, he leaves a mark that immediately catches Kate and Weston's attention: The circumpunct. The symbol of the Beast. But when Kate, Weston, and Christopher journey to Florida to take a closer look, they're sidelined in Apalache Springs, where a friend of Kate's--a retired judge--has been arrested for drunk driving and assault on a police officer. As Kate tries to help her old friend, Christopher soon finds himself controlled by a spirit who wants payback for a decades-old murder. A spirit who sees Kate as the instrument of her revenge.
