G. D. Donleavy

G. D. Donleavy appears to be a mistaken reference to **J. P. Donleavy** (James Patrick Donleavy), an American-Irish novelist and playwright best known for *The Ginger Man*. He was celebrated for satirical fiction that blends ribald humor, black comedy, and comic antiheroes, and he spent much of his life in Ireland.
