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. Follow Professor Challenger on his expedition to the Tepuyes plateau in South America where prehistoric animals and other extinct creatures still roam -- side by side with prehistoric men and vicious ape-like creatures! Edward Malone, a reporter for the Daily Gazette, goes to his news editor, McArdle, to procure a dangerous and adventurous mission to impress the woman he loves, Gladys Hungerton. He is sent to interview Professor George Edward Challenger, who has assaulted four or five other journalists, to determine if his claims about his trip to South America are true. After assaulting Malone, who earns Professor Challenger's respect when Malone refuses to press charges, Professor Challenger reveals his discovery of dinosaurs in South America. Having been ridiculed for years, he invites Malone on a trip to prove his story, along with Professor Summerlee and Lord John Roxton, an adventurer who knows the Amazon and several years prior to the events of the book helped end slavery by robber barons in South America. They reach the plateau with the aid of Indian guides, who are superstitiously scared of the area. One of these Indians, Gomez, is the brother of a man that Roxton killed the last time he was in South America. When the expedition manages to get onto the plateau, Gomez destroys their bridge, trapping them. Their "devoted negro" Zambo remains at the base, but is unable to prevent the rest of the Indians from leaving. Deciding to investigate the lost world, they are attacked by pterodactyls in a swamp, and Roxton finds some blue clay in which he takes a great interest. After exploring the plateau and having some adventures in which the expedition narrowly escapes being killed by dinosaurs, Professor Challenger, Summerlee, and Roxton are captured by a race of ape-men. While in the ape-men's village, they find out that there is also a tribe of humans (calling themselves Accala) inhabiting the other side of the plateau, with whom the ape-men (called Doda by the Accala) are at war. Roxton manages to escape and team up with Malone to mount a rescue. They arrive just in time to prevent the execution of one of the professors and several other humans, including a young man who turns out to be a prince of sorts among the Accala. The rescued Accala then take the party to their tribe. With the help of the expediton's firepower, the Accala defeat the ape-men, taking control of the whole plateau. After witnessing the power of their guns, the human tribe does not want the expedition to leave, and tries to keep them on the plateau. Professor Challenger first plans to fashion a series of balloons to carry the party off the plateau. However, with the help from the young prince of the Accala whom they had saved, the expedition finally discovers a tunnel that leads to the outside, where they meet up with Zambo and a large rescue party. Upon returning to England, they present their report, which include pictures and a newspaper report by Edward. However, many detractors continue to dismiss the expedition's account, much as they had Professor Challenger's original story.
