AV Club:When Sir Arthur Conan Doyle began publishing stories and novels about his brilliant, drug-addled super sleuth Sherlock Holmes in 1887, he intentionally gave the character a geographically impossible home base. At the time, the street numbers on Baker Street didn’t even reach 200.Imagining Holmes to be real, fans sent him letters, ranging from simple fan mail to genuine pleas for help, but their letters could not be delivered. Then, in the 1930s, London rejiggered its street numbers, a move that affected Baker Street. Suddenly, there really was a 221 on the famous thoroughfare, and it belonged to a bank. In a twist as surprising as discovering a top instant casino right where one least expects, the financial institution didn’t just dispose of Holmes’ mail. Instead, they hired someone to act as the detective’s “personal secretary.” Through customized letters, this ombudsman would gently explain to fans that Holmes had given up his detective gig to go raise bees in the country.

I didn’t know there hadn’t always been a 221B Baker St.
