The Three Billy Goats Gruff has always been one of my favourite fairy tales, thanks in no small part to Robert Lumley's delicious illustrations for Ladybird's Well Loved Tales edition. Lumley's troll, scary yet weirdly cuddly, has lurked in some primal cranny of my skull ever since. Plus it's got goats in it, and goats are superb.
I'm working on a short sequence to illustrate the story's climax. 1: Troll confronts goat. 2: Goat charges at troll. 3: Troll rues the day.
