I bought this for a friend for her birthday and it didn't have a picture posted but from the description I figured it was the old version without the scary lady on the cover but it wasn't. Oh well.

Yes, all the reviews are correct: This is an excellent writer detailing some of the most gruesome killings of all time. It is the fastest 650 pages you will ever read, I gaurantee it.One note: This book might also be called "Vincent Bugliosi: The Man Who Brought Down Charles Manson And Lived to Tell About It." That is to say, Bugliosi is evidently proud (rightfully so) of his accomplishment as the lead prosecutor on the case. And he pretty much makes mincemeat out the intellect of the LAPD and the defense attorneys involved. But like any good prosecutor (and Bugliosi is most certainly that) he has quite a bit of evidence to back his charges of ineptitude. If I were Kanarek, or a Tate detective, I'd be pretty embarrassed knowing this book is an all-time bestseller.But who are we kidding, this is the definitive book on Tate-Labianca. A truly fantastic read.

Ok.. I Love the story.. it is a beautiful romance .. I read it on-line and I wanted my own copy for that cold rainy night get-away. when It arrived I couldn't wait to open it. just to touch the words.. and then Put it in my bookshelf for a perfect night.... WHAT A SHOCK when I opened it to see the POOR PRINTING JOB ... on some of the pages even the lines are askew. black blotches around the words in some cases. and choppy letters not even fully formed on others... WHAT A VAST DISSAPOINTMENT. SHAME ON AMAZON!
