Just say no
A copy of this book has turned up on EBay for (get this) $500! Until a few years ago, it was possible to pick up "Thieves" for a few dollars, in fact I found an autographed copy at a Salvation Army store for something like $2. Now, however, prices have hit the stratosphere. The book is utter junk and certainly not worth anything close to $500. Do NOT waste your money on this book. If you want a copy that badly, check it out of the library and take it to Kinko's. Debunking "Thieves" would be a life's work, but trust me, it is the disorganized rant of a disgruntled ex-cop, who published the book himself and was so desperate that he gave away copies and asked people who liked it to send him money. And it says nothing about the Black Dahlia case, regardless of what you may read elsewhere.
