The Lost World

Even though Doyle is most famous for his Sherlock stories, he was also a prolific novelist, and The Lost World is one of his more famous non-Sherlock novels. Like many novels of the day, it was first published serially.
In it we meet a group of adventurers who head to a deep South American jungle to explore rumors of long-lost dinosaurs. The plot is driven by their journey, discoveries, and subsequent narrow escape. Notably, The Lost World is the novel in which Doyle¿s popular recurring character, Professor Challenger, is introduced.
Doyle based many of the characters and locations on people and places he was familiar with: the journalist Ed Malone was modeled on E. D. Morel, and Lord John Roxton on Roger Casement; the Lost World itself was based on descriptions of Bolivia in letters sent to Doyle by his friend Percy Harrison Fawcett.
The novel remains hugely influential and widely adapted today. The title might even remind modern readers of a certain very famous movie franchise about dinosaur theme parks!
