Jack Sheppard is a novel by William Harrison Ainsworth serially published in Bentley's Miscellany from 1839 to 1840, with illustrations by George Cruikshank. It is a historical romance and a Newgate novel based on the real life of the 18th-century criminal Jack Sheppard.
Jack Sheppard was serially published in Bentley's Miscellany from January 1839 until February 1840. The novel was intertwined with the history of Charles Dickens's Oliver Twist, which ran in the same publication from February 1837 to April 1839. Dickens, previously a friend of Ainsworth's, became distant from Ainsworth as a controversy brewed over the scandalous nature around Jack Sheppard, Oliver Twist, and other novels describing criminal life. The relationship dissolved between the two, and Dickens retired from the magazine as its editor and made way for Ainsworth to replace him as editor at the end of 1839.
A three volume edition of the work was published by Bentley in October 1839. The novel was adapted to the stage, and 8 different theatrical versions were produced in autumn 1839.
The story is divided into three parts called "epochs". The "Jonathan Wild" epoch comes first. The events of the story begin with the notorious criminal and thief-catcher Jonathan Wild encouraging Jack Sheppard's father to a life of crime. Wild once pursues Sheppard's mother, and eventually turns Sheppard's father over to the authorities, and he is soon after executed. Sheppard's mother is left alone to raise Sheppard, a mere infant at the time.
Paralleling these events is the story of Thames Darrell. On 26 November 1703, the date of the first section, Darrell is removed from his immoral uncle Sir Rowland Trenchard, and is given to Mr. Wood to be raised.
The third epoch takes place in 1724 and spans six months. Sheppard is a thief who spends his time robbing various people. He and Blueskin rob the Wood's household, when Blueskin murders Mrs. Woods. This upsets Sheppard and results in his separation from Wild's group. Sheppard befriends Thames again and spends his time trying to correct Blueskin's wrong.
