A subgenre of British fiction in the 1830s and 1840s that romanticized real criminals from the Newgate Calendar — including Paul Clifford (Bulwer-Lytton, 1830) and Jack Sheppard (Ainsworth, 1839). The Newgate novels were the immediate ancestors of Victorian sensation and detective fiction, and the controversies they provoked helped shape the genre's enduring moral self-defense.
