John Stuart Roberts was the editor of BBC TV’s Everyman and Heart of the Matter, and is a former head of television, BBC Wales. He first read Sassoon’s work in a second-hand bookshop in Swansea in 1958, and from then on made the poet a lifetime’s study.

An essentially private person, Siegfried Sassoon's work nevertheless constitutes a chorus of self-revelation. John Stuart Roberts has written the first full length biography of this complex man. A quintessential Edwardian gentleman, who celebrated the English countryside in his much-loved quasi-autobiography, "The Sherston Trilogy", Sassoon nevertheless owed his poetic vision to Sephardic Jewish roots abandoned by his dilettante father before his son's birth. His friendships and contacts ranged widely from Thomas Hardy and Edmund Gosse to the Sitwells, Wilfred Owen, Edmund Blunden, Rupert Brooke, T.E. Lawrence, Eddie Marsh and Stephen Tennant. In writing this biography, John Stuart Roberts has had access to much unpublished material, including the Hart-Davis papers which contain the diaries covering the last 30 years of Sassoon's life, and also to correspondence between Sassoon and Eddie Marsh, Edmund Blunden and Dame Felicitas Corrigan OSB. His interviews have ranged from Mother Margaret Mary to cricketer Dennis Silk and poet Ian Davie.

Sassoon's homosexuality is examined sensitively, and the war poems are discussed in full, while his inner journey to Catholicism in his final years is charted.
