My job is not to frighten children, but sometimes addressing fears and concerns within the safe boundaries of a picture book can fill me with an awesome responsibility to be as truthful and transparent as possible.
Books are mind reading devices; they allow us free access to the thoughts and dreams of people we have never met.
Despite the fact the studio looks out of five windows onto a picture perfect view of sky, hills and wide open spaces, I work with my blinds firmly drawn, daylight filtered through their white canvas, a painterly northern light falling through two big skylights above my table, and nothing visible outside to distract me.
No ideas are harmed in the making of my books, by the way. All I do with my best ideas is run with them, fast as I can, taking notes and occasionally suggesting a left hand turn rather than the right hand one which might have taken us both over a precipice.
There are whole months at a time when my head is so full of ideas that I wake in the middle of the night and lie in the dark telling myself stories. There are also long, dark nights when I just know I'll never write another word: I'm finished, empty, a husk... Oh dear, yes, twitch, yawn, how I've suffered insomnia for my art.
