This is the fourth book in the Manny Williams Series. Lansing Detective, Manny Williams, took the plunge. He accepted the FBI's offer to join the elite Behavioral Analysis Unit, much to the delight of the unit's supervisor, Josh Corner. Two months later, he was joined by his old partner, Sophie Lee, and Lansing's top CSI, Alex Downs. With his nemesis, serial killer Fredrick Argyle, six feet under and Manny's love life making a comeback, it seemed that life was finally back on the high road until his first assignment. A vicious killer is running amok in El Yunque, Puerto Rico's lush rainforest, and taking no prisoners, only body parts. Manny and the crew are called in, but they're too late. One of their own has fallen victim to the maniac's rampage and the killer isn't finished. Not by a long shot. Rick Murcer is a New York Times Best Seller and a USA Today Top Ten Selling author.
