Stuart: A Life Backwards is a biography by Alexander Masters concerning Master's friend Stuart Clive Shorter, formerly, at various times, a prisoner and a career criminal. It explores how a young boy, disabled from birth, became mentally unstable, criminal and violent, living homeless on the streets of Cambridge. As the title suggests, the book starts from Shorter's adult life, and works backwards to trace through his troubled childhood, examining the effects his family, schooling and disability had on his eventual state.

The book won the Whitbread Book of the Year Award in 2005 for biography, and the 2006 Hawthornden Prize.^{[unreliable source?]} It won the 2005 Guardian First Book Award.

A stage production premiered in 2013 adapted by double BAFTA-winning writer Jack Thorne produced by HighTide Festival Theatre and the Crucible Theatre Sheffield.

Stuart Shorter (born Stuart Clive Turner on 19 September 1968 in Cambridge – died 6 July 2002 in Waterbeach, Cambridgeshire) was a homeless man and advocate whose life was chronicled by Alexander Masters in his book.

Shorter was born in a condemned cottage on the edge of Cambridge, the son of Andrew Turner (called Rex in the book and dramatisation), a gypsy and Sonia (Judith), (née Tierney), a barmaid. Sonia later remarried, to David Shorter [Paul]. Stuart had two brothers and one half-sister, Andrew [Gavvy], Kai [Marcus] and Zoe [Karen]: most noted in the novel are his older brother, Gavvy, and younger sister, Karen. Marcus is only mentioned briefly in the book. Shorter suffered from facioscapulohumeral muscular dystrophy, which he inherited from his father, and borderline personality disorder.

As a child, Shorter was sexually abused by his brother, and also by a babysitter, after which he was put into a children's home. Here, he was abused again by the paedophile Keith Laverack, who in 1997 was jailed for 18 years for various offences against children. During his adult life, Shorter was in and out of various homeless hostels, as well as spending much time in prison for a number of violent crimes. He also fathered one son, the Little'Un, who lives in Norwich.

In 1998, following a five-year jail sentence for armed robbery, Shorter was living in a subterranean multi-storey car park when he was rescued by two outreach workers, who found him a flat to live in. He subsequently became one of the first people to bring The Big Issue into Cambridge, and his work as an activist for the homeless began when he presented a short BBC2 documentary, Private Investigations, denouncing police plans to ban homeless people from the city centre.
