By John Douglas and Mark Olshaker. The second book from the FBI's legendary (just ask him) profiler. A little too self-congratulatory overall, but his insights into the murders of Nicole Brown Simpson and Ronald Goldman were fresh at the time.
This paperback isn't fresh, exactly, but it's in decent shape: page toning, mild edgewear, and a spine crack, but it's square and tight -- a good reading copy for Douglas/Olshaker completists.
