Prompt from Wordwielder: Piano

The gentle melody of the piano drifted through the air, the crowd reduced to admiring whispers as they listened.

In a quiet side room, the lilt provided cover for a hushed conversation. "You must go, Sherlock. No less than the fate of our country is at stake."

"I am retired, Mycroft. My mind is not as sharp as it was. There must be another who can help you, someone younger, more prepared for this new age."

"You know as well as I that there is no one. Even your young protege at the Yard does not have the skills you have."

"Skills you have as well."

"Deduction, certainly. But your talent for disguise? Of chasing down clues? Really, Sherlock."

"…You will tell Watson?"

"I will."
