The Hound of the Baskervilles

 was a Sherlock Holmes novel by Arthur Conan Doyle. It was the first Holmes novel Doyle had written since the character's death in The Final Problem.

The real reason why Doyle chose to write the novel was to save himself, Professor George Litefoot, Henry Gordon Jago, and Laura Lyons from the mercy of Roger Baskerville. Lyons and Baskerville were time travellers from the 63rd century that had become stranded in the distant past when the latter purposely killed the other scientists on the mission after falling in love with Lyons. Not realising Holmes was a work of fiction, Laura wrote to him and arranged a meeting at 221B Baker Street after escaping from Baskerville. After a brief meeting, Laura was recaptured by Baskerville with Jago, Litefoot, and Doyle soon following through the temporal barrier. Faced with immediate mortal peril from Baskerville's dogs, Litefoot made Doyle promise to write one more Holmes novel with a character called Laura Lyons and an antagonist called Baskerville to send a message of their namesake's whereabouts to the 63rd century. The plan worked and a rescue party came to rescue Laura and arrest Baskerville. (AUDIO: The Monstrous Menagerie)

The Doctor had read the novel by his eighth incarnation. The Eighth Doctor quoted the book after being chased by a dog in Dartmoor. (PROSE: Camera Obscura)

Ian Chesterton read the novel prior to 1963. (AUDIO: The Revenants)
