By John Douglas & 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.
Average wear to this PB: some edgewear, some page toning, a cracked spine…but it sits straight, no markings inside. A solid reading copy.
