In the Belly of the BeastBy: Jack Henry Abbott A visionary book in the repertoire of prison literature. When Normal Mailer was writing The Executioner's Song, he received a letter from Jack Henry Abbott, a convict, in which Abbott offered to educate him in the realities of life in a maximum security prison. This book organizes Abbott's by now classic letters to Mailer, which evoke his infernal vision of the prison nightmare.
