The Lost World is an adventure and science fiction novel by British writer Sir Arthur Conan Doyle recounting an expedition to a remote plateau in the Amazon basin of South America where dinosaurs and other prehistoric animals still survive, along with a tribe of vicious ape-like creatures that are in conflict with a group of indigenous Indians. The work introduces the character of Professor Challenger, who leads the expedition (and who would appear in later Conan Doyle stories), and is narrated in the first person by the journalist member (Edward Malone) of the exploration party. The Lost World appeared in serial form in the Strand Magazine, illustrated by New-Zealand-born artist Harry Rountree, during the months of April through November 1912 and also was serialized in magazines in the United States from March to November 1912. Hodder & Stoughton published the first book edition in October 1912 in Great Britain (London), with printings as well in the United States (New York) and in Canada (Toronto).
When he was working on The Lost World, Doyle explained to his editor Herbert Greenhough Smith: "My ambition is to do for the boys' book what Sherlock Holmes did for the detective story". Doyle cast the novel in the mode of the popular 19th century "boy’s adventure story" genre of Robert Louis Stevenson and H. Rider Haggard, but written to appeal to adults as well, as declared in his opening epigraph:
