Interesting bit of trivia for Sherlockians:
When you hear the phrase “The game is afoot!” what do you first think of? Sherlock Holmes, of course. He says it at the beginning of “The Adventure of the Abbey Grange,” and it’s one of the many lines adapted for Sherlock (“The game, Mrs. Hudson, is on!”). But in fact, when Sherlock said it, he was quoting someone else. Shakespeare, to be exact. The line comes from Act 3, Scene 1 of Henry V.
How to know when a character has really made it big? When a Shakespeare quote is more often associated with him than it is with Shakespeare.
