The "Just William" series is a sequence of thirty-nine books written by English author Richmal Crompton. The books chronicle the adventures of the unruly schoolboy William Brown.

William Brown is an eleven-year-old schoolboy in a village in England. Leader of the Outlaws, William is unique in schoolboy literature – confident, strong-willed, independent-minded with original world-views, a born leader who is keen to be chief in any undertaking of the Outlaws.

He does not care about his clothes or appearance, wears a scowl as his best "company manners" and hates small talk. He loves to play Red Indians and pirates, and readily embarks on any project, from catching wartime spies or making a "moon rocket", to editing a "newspaper" or organising a "circus" or "show", often featuring his pet dog Jumble as reluctant star.
