"Sammy's seems a good kid."

"Hmm. What's the story with the skull?"

Sherlock looked up at the mantlepiece.

"Someone who won't answer back, or sell your secrets?"

"Something like that." Picking up the violin, Sherlock settled it under his chin and after a few tentative strokes of the bow he started to play a sonata, lifting himself from the chair and moving to stand to one side of the fire.

John sighed. "That was beautiful."
