By Robert K. Ressler & Tom Shachtman. Ressler "coined the phrase 'serial killer' and advised Thomas Harris on The Silence of the Lambs," and this is a must-read in the genre -- as important as John Douglas's work, but less self-important, too.
This first-edition hardcover is in fine fettle: slight shelfwear/rubbing to the jacket, and the back flap has a crease, but nice and bright inside, sits straight. A nice reading copy with which to cross it off your lifetime true-crime-TBR list.
