I'm almost done reading Mark Frost's
The Secret History of Twin Peaks which is cited as being a novel, but it's not really. It's a dossier of related (fictional) articles pertaining to the history of Twin Peaks and its residents. It is annotated by FBI Agent T.P. who we now know from season 3 is Tammy Preston. Some parts are more successful than other, for example it spends too much time discussing UFO sightings and extra terrestrial intrigue although it feels like it's culminating into something more esoteric. Highlights so far have included Big Ed and Norma's relationship, the Horne's and the Packard's and especially Josey's history and attachment to the Triads of Hong Kong.
It's a fantastic looking book! I'm really looking forward to the next edition which is called 'The Final Dossier' and I think it relates more to the Laura Palmer case.
