By John Douglas and Mark Olshaker. An underrated compendium from one of the founders of the FBI profiling program -- and while Douglas's self-promotion tends to be ruthless elsewhere, it's less intrusive here. Cases include not just Jack and JonBenét but Bembenek, Black Dahlia, the Lindbergh kidnapping, the Boston Strangler, and others. I've come back to this one many times.
A decent paperback with corner- and edgewear and a cracked spine, but it sits straight and trim, pages are clean. And there's a free recipe inside! (...I don't know either.)
