The Lost World, undoubtedly the most famous non-Sherlock Holmes story written by Sir Arthur Conan Doyle, was published in 1912 in the Strand magazine. Despite the popularity of Holmes, Conan Doyle himself preferred either his historical work or fantastical stories. Edward Malone, the main character, is a young man in love; but the woman of his dreams, Gladys, is critical of him because he has never done anything spectacular or dangerous to prove his love for her. Malone, who works as a journalist for the Daily Gazette, quickly finds a way to impress Gladys: he decides to take part in the expedition of Professor George Edward Challenger, a zoologist whose scientific reputation has been damaged by his insistence that creatures thought to be extinct still exist within the Amazon basin. During this expedition – made up of Professor Challenger, Professor Summerlee, the Amazon adventurer Lord John Roxton, and Malone – the young journalist discovers a lost world full of dangers and incredible creatures.
