(For the TV series, see The Secret Diary of Adrian Mole (TV series).) Adrian Albert Mole is the fictional protagonist in a series of books by English author Sue Townsend. The character first appeared (as Nigel) in a BBC Radio 4 play in 1982. The books are written in the form of a diary, with some additional content such as correspondence. The first two books appealed to many readers as a realistic and humorous treatment of the inner life of an adolescent boy. They also captured something of the zeitgeist of the UK during the Thatcher period.
