The famous Sherlock Holmes catchphrase "The game is afoot" is taken from Act I, Scene 3, line 615, where the Earl of Northumberland says: "Before the game is afoot, thou still let'st slip."
The phrase was also later used by Shakespeare in Henry V, Act III, Scene 1, by the title character:
- "I see you stand like greyhounds in the slips,
- Straining upon the start. The game's afoot:
- Follow your spirit, and upon this charge
- Cry 'God for Harry, England, and Saint George!'"
