Room 1219: The Life of Fatty Arbuckle, the Mysterious Death of Virginia Rappe, and the Scandal that Changed Hollywood By: Greg Merritt

I didn't know I needed this book until I finished it!  An in depth look at the Arbuckle/Rappe case, which also includes, or more accurately is interwoven, with the history of comedy, Hollywood, films, the Hays office, and celebrity culture.  It's an astonishing array of information imparted brilliantly, and simply.  A must for fans of old Hollywood and/or true crime.
