Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis Stevenson (November 1850- December 1894) is one of the most popular stories of “the second self”. Told mainly from the perspective of lawyer Mr. Utterson, the story follows him as he works to solve the mystery of his friend Dr. Jekyll as well as the murder of one of his clients by a man called Mr. Hyde. While watching the decline of Dr. Jekyll, Mr. Utterson slowly begins to put the pieces together, and all is resolved by a direct confession by the doctor. He tells of how he created a drug that would allow him to split himself into two: Dr. Jekyll as the good version and Mr. Hyde as the evil version. After running out of one of the ingredients of the drug, Dr. Jekyll realized that he would be permanently transformed as Mr. Hyde. After writing his account of events, he locked himself in his laboratory and poisoned himself. The novel was very well received and has been widely adapted.
