The "Curse" of the 221B Mailbox

When the Abbey National Building Society moved its headquarters to Baker Street in the 1930s, their address happened to encompass the fictional 221B Baker Street. They were instantly flooded with thousands of letters addressed to Sherlock Holmes from people all over the world begging for help. The bank actually had to hire a full-time, permanent secretary whose sole job description was to reply to these letters with a template stating: "Mr. Holmes has retired to Sussex to raise bees."
