Sir Arthur Ignatius Conan Doyle was a British writer best known for his detective fiction featuring the character Sherlock Holmes. Originally a physician, in 1887 he published "A Study in Scarlet", the first of four novels about Holmes and Dr. Watson. In addition, Doyle wrote over fifty short stories featuring the famous detective. The Sherlock Holmes stories are generally considered milestones in the field of crime fiction. Doyle was a prolific writer; his non-Sherlockian works include fantasy and science fiction stories about Professor Challenger and humorous stories about the Napoleonic soldier Brigadier Gerard, as well as plays, romances, poetry, non-fiction and historical novels.

THE HOUND OF THE BASKERVILLES
Fiction
Dr. James Mortimer asks Sherlock Holmes to investigate the death of his friend, Sir Charles Baskerville. Sir Charles was found dead on the grounds of his Devonshire estate, Baskerville Hall, and Mortimer now fears for Sir Charles's nephew and sole heir, Sir Henry Baskerville, who is the new master of Baskerville Hall. The death was attributed to a heart attack, but Mortimer is suspicious, because Sir Charles died with an expression of horror on his face, and Mortimer noticed "the footprints of a gigantic hound" nearby. The Baskerville family has supposedly been under a curse since the era of the English Civil War when ancestor Hugo Baskerville allegedly offered his soul to the devil for help in abducting a woman and was reportedly killed by a giant spectral hound. Sir Charles believed in the curse and was apparently fleeing from something in fright when he died.

THE LOST WORLD
Fiction
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, 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.
