In The Adventure of the Charles Augustus Milverton, Holmes and Watson go undercover to burgle a blackmailer’s house. To prepare for the heist, Holmes forces Watson to dress up in a very specific, rough working-class outfit. However, Conan Doyle completely forgot to explain where they changed or what they did with their normal clothes. Fans on literary forums frequently joke about the image of Victorian London's greatest detective duo running through the foggy streets of London in their underwear, carrying bundles of tweed trousers.
