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.
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.
