Based on the best-selling series of boarding school books written by Geoffrey Willans and illustrated by Ronald Searle, Molesworth tells the story of Nigel Molesworth, a self-confident, tousle-haired public school boy with a mischievous nature and a penchant for power.

The character was first drawn by Ronald Searle for his Punch magazine comic strip and later developed into a series of books, first published in 1953.
