Book excerpt: Over the course of his nearly forty-year career, John Douglas has pursued, studied, and interviewed criminals including Charles Manson, James Earl Ray, Dennis Rader, and David Berkowitz - a veritable Who's Who of violent predators. But he has also devoted extensive energies to helping the wrongfully accused and convicted, including several inmates of death row. Now, with longtime collaborator Mark Olshaker, Douglas addresses every law enforcement professional's worst nightmare: cases in which justice was delayed, or even denied. Book jacket.
