Our annual Halloween ghoul-fest never fails to deliver the chills and this year's line up will be no exception. Hammer versus Amicus? Horror writer Christopher Fowler debates with radio producer Simon Hollis in this battle of the horror franchises, alongside R4 presenter and author of Shepperton Babylon, Matthew Sweet. Christina Oakley Harrington gives us the inside story on running an occult bookshop (the marvellous Treadwells in Bloomsbury), while author and founder member of Blondie Gary Lachman discusses his biography of Aleister Crowley, Magick, Rock and Roll, and the Wickedest Man in the World. Presided over as usual by Suzi Feay. Do not miss!
