As a child I buried myself in books both at home in Essex and at my grandparents’ houses in Cornwall, where I spent a large part of my time, and where many of my stories are now set. Books and later films were an escape not just from where I was but who I was, which, as I saw it, was pretty much a geek. They gave me the freedom to become someone else, from George in the Famous Five to Velvet Brown winning the Grand National to Baby dancing the Chachacha with Johnny Castle.
