What is Sherlock first words to Moriarty?

There's no record of Sherlock Holmes ever directly speaking to Moriarty in Sir Arthur Conan Doyle's original stories.

Moriarty is primarily a shadowy figure, the criminal mastermind who operates behind the scenes. Their encounters are usually indirect, through clues, coded messages, or their respective agents.

While there are famous lines associated with Moriarty, like "The game is afoot!" (attributed to Sherlock Holmes), they are never directly addressed to Moriarty himself.
