A special guided ghost walk for Halloween. We'll be exploring ghostly goings-on in High Barnet, and Monken Hadley, the second most haunted village in England. It's a fun and informative walk, ideal for all ages. There's some audience participation, so watch out! Please bring a torch/phone, as we'll be going through a churchyard. And you're invited to dress up in costume -- no obligation. With Paul Baker, City of London guide. £12, £5 under 12s
