My parents also have a leather bound edition of The Pilgrim's Progress which is told in caption/cartoon style with fantastic (in every sense) drawings of the main characters. The hobgoblins are convincing (and I'm sure gave me more than one nightmare when I was a kid, but then that would fall within their job remit). So since I was very young I've been immersed in fantastic stories and they, to me, just seem the right thing to write.
I think the reason I love fairytales so much is they are honest, often funny stories dealing with what comes up in the battle between good and evil (and I adore the fact the villains nearly always get their comeuppance). Like most kids, gruesome ends for those who deserved it always went down well, as that genius, Roald Dahl, knew.
