The Mad Hatter is a fictional character initially encountered at a tea party in
Lewis Carroll's
Alice's Adventures in Wonderland. The chapter in which he first appears, "A Mad Tea-Party", is often erroneously called "The Mad Hatter's Tea Party" but in fact it takes place in the garden of the
March Hare. Later in the book, when the Hatter is summoned to give his evidence at the Knave of Heart's trial to uncover who stole the Queen's tarts, the King prompts him by saying "Don't be nervous or I'll have you executed on the spot." The Hatter makes another appearance in the sequel
Through the Looking-Glass as Hatta, one of the White King's messengers.
