London is the capital city of England and is also the central environment where many British-written stories take place. Specifically, Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis Stevenson and Never Let Me Go by Kazuo Ishiguro take place in or around this area specifically. Being the capital of England, it has a rich history of cultural and economic influence on a global scale. Because of its influence, a lot of the works produced that feature London as a primary setting feature themes of British identity and the ideas and conceptualizations that surround what it means to have an identity that is British, especially in an area that flows with wealth and influence. Strange Case of Dr. Jekyll and Mr. Hyde in particular deals with the idea of ones reputation, and the concealment of things that make them themselves, and the consequences that might have on the identity of the population.
