The Redheaded League

This is the second short story in The Adventures of Sherlock Holmes. It doesn't have an Episode yet, but something that Holmes says is similar to what Sherlock says in A Study in Pink. In The Redheaded League, Watson asks, "What are you going to do, then?" To which Holmes replies, "To smoke. It is quite a three-pipe problem". In A Study in Pink, when John returns from meeting Mycroft, Sherlock is lying on the couch with three nicotine patches on his arm. John asks, "You've got three". To which Sherlock replies, "It's a three patch problem". I think it's funny that they flipped it. But it kinds makes sense considering that Benedict Cumberbatch doesn't smoke.
