Whew. Well. Despite being an almost intensely eloquent individual, little I could say would do this book justice. It's all new material. Must've taken months to create. And we'd still have bought it if it were just bits of old scripts. They must be a few toads short of an amphibarium.
You want your favourite characters? They're here, with more new and interesting information than you could ever envisage...You want to see inside the minds of its creators? Just look at the map of Royston Vasey, with place names involving film, television and literary references beyond the dreams of critics...So you think Royston Vasey actually exists, and that the LoG are just a group of camera men who cleverly film the whole thing without the inhabitants realising it?...well, it doesn't say so in the book, but you're about to learn that Royston Vasey is as real as the place you were born...though hopefully a little more frightening (or else I dread to think about the upbringing you must've had, you poor beggar). Read. Laugh. Cry if you feel the impulse (but don't wet the pages - this book is worth its weight in Special Stuff).
It also includes the complete lyrics of Voodoo Lady, part of a Legz Akimbo script (as performed in their spectacular stage show - worth reading if you haven't seen it, and well worth revisiting if you have), the original story of The Curse of Karrit Poor (for Sherlockians and Leaguers alike, the words of this piece are of the purest gold), some terribly dark and disturbing information about Edward (his localness comes into question...how can this be?!) and many photos, diary entries, and bits of documents which the inhabitants of Royston Vasey never wanted you to read!
Go on, buy it! It costs less than Iris owes "Kay's" catalogue (thought that's not saying much...)
