Which fictional character lives at 221B Baker Street, London?

221B Baker Street, London, is known worldwide as the residence of the fictional genius, private detective Sherlock Holmes.

But it’s also a real building in London, with a mystery of its own that's coming to fruition: no one knows who owns it.

Baker Street in the late 19th century was a high-class residential district, and Holmes's apartment would probably have been part of a Georgian terrace.

Sherlock Holmes is a fictional private detective created by British author Sir Arthur Conan Doyle. Referring to himself as a "consulting detective" in the stories, Holmes is known for his proficiency with observation, deduction, forensic science, and logical reasoning that borders on the fantastic. Most are narrated by the character of Holmes's friend and biographer Dr. John H. Watson, who usually accompanies Holmes during his investigations and often shares quarters with him at the address of 221B Baker Street, London, where many of the stories begin.
