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 fine shape for its age -- cornerwear, a smudge to the page edges -- but the spine is uncracked, it sits very straight. A nice reading copy.
