The Lost World is a novel released in 1912 by Sir Arthur Conan Doyle concerning an expedition to a plateau in the Amazon basin of South America where prehistoric animals (dinosaurs and other extinct creatures) still survive. It was originally published serially in the popular Strand Magazine and illustrated by New-Zealand-born artist Harry Rountree during the months of April-November 1912. The character of Professor Challenger was introduced in this book. The novel also describes a war between indigenous people and a vicious tribe of ape-like creatures. PLOT: Edward Malone, a reporter for the Daily Gazette, asks his news editor, McArdle, for a dangerous and adventurous mission in order to impress the woman he loves, Gladys Hungerton. He is sent to interview the cantankerous Professor Challenger, who has become notorious for claims made about his recent expedition to South America. The professor has been plagued by intrusive reporters and, being a formidable man of great strength, has taken to forcibly ejecting them, despite the resulting police prosecutions. To gain entry Malone pretends to be an honest enquirer, but is quickly discovered, assaulted and thrown into the street. Although this is witnessed by a policeman, Malone does not press charges as the original deceit was his. Challenger is suitably impressed, and decides to reveal something of his discovery of living dinosaurs in South America. Malone is invited to a scientific gathering that evening at which he volunteers, along with the biologist Professor Summerlee and the Amazon adventurer Lord John Roxton, to travel to South America to investigate the claims. After a long and arduous journey through Brazil, the explorers reach a volcanic plateau jutting far above the jungle. Upon climbing up to the plateau, one of their local guides who has a score to settle with Roxton destroys their temporary bridge across a precipice, trapping the explorers on the dinosaurs' plateau. The explorers encounter five iguanodons and are later attacked by pterodactyls, and Roxton finds some blue clay in which he takes a great interest. After numerous encounters with dinosaurs, Challenger, Summerlee, and Roxton are captured by a race of 'ape-men'. While in the ape-men's village, they discover a tribe of anatomically-modern humans (calling themselves Accala) inhabiting the other side of the plateau, with whom the ape-men (called Doda by the Accala) are at war. With the help of the expedition's firepower, the Accala conquer the ape-men; and insist that the expedition remain on the plateau. With the help from the young prince of the Accala, whom they had saved from the ape-men, the expedition discover a tunnel to the outside world, where they join a large rescue party. Upon return to England, they present their report, which include pictures and a newspaper report by Malone, but they are disbelieved by the public until Challenger shows as proof a live pterodactyl, which then escapes into the Atlantic Ocean. At dinner, Roxton reveals that the blue clay contains diamonds, about £200,000 worth, to be split between them. Challenger plans to open a private museum, Summerlee plans to retire and categorize fossils, and Roxton plans to return to the lost world. Malone returns to his love, Gladys, only to find that she had married a solicitor's clerk in his absence. He therefore volunteers to join Roxton's voyage...
