The Anatomy of Motive: The FBI's Legendary Mindhunter Explores the Key to Understanding and Catching Violent Criminals

By John Douglas and Mark Olshaker. The fourth of Douglas and Olshaker's mass-market books, which focuses on profiling "the antisocial personality" and its most notorious exemplars (Oswald, McVeigh, et al.).  The paperback's in average shape for its age -- edgewear, some marks to the page edges, a cracked spine -- but sits pretty straight and is a serviceable copy if you're looking to complete the authors' run.
