House M.D. is loosely based on which literary detective?

House M.D. is loosely based on Sherlock Holmes, the detective created by Arthur Conan Doyle. The connection appears in the show’s character names, themes, and method of solving cases.

House’s surname resembles Holmes, and his investigative process relies on observation, deduction, and the elimination of competing explanations. Dr. James Wilson functions as a Watson-like friend and sounding board, while House’s address, 221B Baker Street, is echoed through details associated with the character in the series.

The parallel is not a direct adaptation of a particular Holmes story. House investigates medical mysteries rather than crimes, and the patient’s symptoms take the place of physical clues. His drug dependence and difficult personality also recall Holmes’s more troubled traits, although the television character has his own backstory and relationships.

The show frequently uses misdirection and a final revelation, techniques familiar from detective fiction. This framework helped House M.D. distinguish itself from conventional hospital dramas by making diagnosis an intellectual mystery as well as a medical procedure.
