In 1957 at the age of 17, Moorcock became editor of "Tarzan Adventures" (a national juvenile weekly featuring text and Tarzan comic strip), where he published at least a dozen of his own "Sojan the Swordsman" stories during that year and the next. At age 18 (in 1958), he wrote the allegorical fantasy novel "The Golden Barge". This remained unpublished until 1980, when it was issued by Savoy Books with an introduction by M. John Harrison. At 19 years of age Moorcock also edited "Sexton Blake Library" (serial pulp fiction featuring Sexton Blake, the poor man's Sherlock Holmes) and returned to late Victorian London for some of his books. Writing ever since, he has produced a huge volume of work. His first story in "New Worlds" was "Going Home" (1958; with Barrington J. Bayley). "The Sundered Worlds", a 57-page novella published in the November 1962 number of "Science Fiction Adventures", edited by John Carnell, became, with its sequel "The Blood Red Game" from the same magazine, the basis for his 190-page paperback debut novel three years later, "The Sundered Worlds" (Compact Books, 1965; in the U.S., Paperback Library, 1966).
