Journey Into Darkness: The FBI's Premier Investigator Penetrates the Minds and Motives of the Most Terrifying Serial Killers

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. Some shelfwear on this paperback, some foxing from storage as shown, but an uncracked spine and clean inside (one tiny accidental dog-ear) -- a good reading copy for Douglas/Olshaker completists.
