Author's Note

'Why didn't you wear the hat today?' John questioned as he hung his coat.

'I wear the hat when I want t-' Sherlock stopping in mid sentnce wasn't unusual but it was his expression that shockes John. It was that of pure shock and anger. 'Do you hear that?'

At first, John heard silence but the more he waited, the more he heard it. A violin playing Ring Around the Roses in a merry fashion.
