Everyone's favourite troublemaker is back in Richmal Crompton's William the Bad - with a fun and contemporary cover illustrated by Chris Garbutt and an introduction by writer Anne Fine.

William doesn't understand why he's not invited to Robert and Ethel's fancy-dress party - what could possibly go wrong? Desperate for an invite, his search for the perfect costume causes mayhem. Somehow nothing ever goes to plan when William the Bad is around!

There is only one William. This tousle-headed, snub-nosed, hearty, lovable imp of mischief has been harassing his unfortunate family and delighting his admirers since 1922.

Enjoy more of William's adventures in William's Happy Days and William Again.
