Denton Welch was born on 29 March 1915 in Shanghai, the youngest of three brothers. Welch was sent back to England to attend St Michael's prep school in Uckfield, and then Repton School, where his main achievements were in art. Soon after his sixteenth birthday he ran away from school. With his family's approval he enrolled at the Goldsmiths' School of Art in April 1933 to study painting. He showed great promise as an artist but in June 1935, while still a student, he was knocked off his bicycle by a motorist, severely damaging his spine and kidneys; for the rest of his life he was a semi-invalid. Welch settled in Kent, in a succession of rented flats and cottages. His final home was in the village of Crouch, where his faithful friend Eric Oliver cared for him until his premature death on 30 December 1948.

Maiden Voyage is an account of author Denton Welch's sixteenth year, when he ran away from his English public school and was then sent to Shanghai to live with his father. The book was Welch's first and created a sensation on publication in 1943; its frank description of public schoolboy life forced publisher Herbert Read to initially seek advice from libel lawyers. Even Winston Churchill's private secretary gossiped in a letter that, "the book was reeking with homosexuality? I think I must get it." Today, Welch's expressions of sexuality may seem more demure than outrageous, but his portrayal of the passions and humiliations of adolescence is graphic. As in all of Welch's novels, it is the precisely realized details of the author's physical and social surroundings that make the book such a remarkable journey.
