Growing up
I grew up in a tall Victorian London house with my parents, grandmother, aunt, uncle, younger sister Mary and cat Geoffrey (who was really a prince in disguise. Mary and I would argue about which of us would marry him).

My real breakthrough was THE GRUFFALO, again illustrated by Axel. We work separately - he’s in London and I’m in Glasgow - but he sends me letters with lovely funny pictures on the envelopes.

I really enjoy writing verse, even though it can be fiendishly difficult. I used to memorise poems as a child and it means a
