Exclusive: Two-page 1957 manuscript signed by author linked to his classic of beat literature On the Road

A “very significant” unpublished story by Jack Kerouac described as “a lost chapter of the On the Road saga” has been discovered after languishing in the files of an assassinated Mafia crime boss for at least 40 years.

The two-page typewritten manuscript signed by Kerouac in green ink is titled The Holy, Beat, and Crazy Next Thing and is dated 15 April 1957, five months before his classic of beat literature, On the Road, was published.

It was discovered last year during the disposal of items owned by Paul Castellano, who ran the feared Gambino crime family in New York from 1976 until he was murdered in a hail of gunfire on 16 December 1985.

The assassination was orchestrated by John Gotti, a Gambino boss who was dissatisfied with Castellano’s leadership and took over the organisation after the hit. He was convicted of the murder of the 70-year-old Castellano in 1992 and died in prison 10 years later.
