Deathworld is the name of a series of science fiction novels by Harry Harrison including the books Deathworld (first published 1960, serialized in Astounding Science Fiction), Deathworld 2 (1964, initially titled The Ethical Engineer and serialized in Analog) and Deathworld 3 (1968, serialized in Analog as The Horse Barbarians), plus the short story "The Mothballed Spaceship" (1973, written as part of a tribute to John W. Campbell). The central hero is a gambler who becomes involved with colonists of an extremely hostile planet. There are several hints that the novels take place in the same universe as Harrison's The Stainless Steel Rat series; however, other hints suggest a similar universe but not exactly the same one. For example, at several points in the Deathworld series, the novels mention the Special Corps with Inskipp as its leader; however, the story "The Mothballed Spaceship" mentions an armada about to attack Earth.a planet that is long destroyed in the time of The Stainless Steel Rat universe.
