As a child, I copied Tenniel's illustrations from 'Alice's Adventures in Wonderland' obsessively, particularly his drawing of the white rabbit in waistcoat and frockcoat, umbrella tucked under one arm and a fob watch in paw, a look of suppressed panic in his eye.

I think stories can grow out of the visual. It can be an engine for literacy.

The writing process isn't something I'm in love with. I'm an illustrator who writes.

Roald Dahl worked with other illustrators, but it was only when he teamed up with Quentin Blake that the chemistry began to fizz. Quentin Blake is Britain's greatest living illustrator and has that special talent all the great illustrators have, of unobtrusive brilliance.
