The Sherlock Holmes Museum

This guide to the Sherlock Holmes Museum in London follows the decades of fan mail addressed to 221B Baker Street, an address Arthur Conan Doyle invented in 1887 before the street ever reached that number. It traces how a bank moved into the site in the 1930s and found itself fielding letters meant for a detective who never existed, right down to hiring someone to answer them. Listen for the standoff that followed once the museum itself opened in 1990.
