Which Sherlock Holmes character is Gregory House’s closest literary counterpart?

Gregory House is the closest Sherlock Holmes counterpart in House M.D.

The series deliberately models House on Arthur Conan Doyle’s detective. Both characters are brilliant investigators who solve difficult cases through observation, deduction, and attention to clues that others dismiss. House’s surname also resembles Holmes’s, and both figures are known for abrasive personalities and unconventional methods.

James Wilson functions as a counterpart to Dr. John Watson, Holmes’s friend and companion. The parallel extends to details such as House’s apartment number, 221B, which echoes Holmes’s address at 221B Baker Street. House’s drug dependence also recalls Holmes’s use of cocaine in the original stories, although the substances and circumstances differ.

House is not simply a modern version of Holmes: he is a physician, and each episode frames a medical diagnosis as an investigative mystery. The show adapts the detective structure while placing it in a teaching hospital and replacing crimes with unexplained illnesses.
