With cherries on top? It’s the Jeremy Brett television series and the episode is called The Master Blackmailer.
The song starts at 10.20
and also the music is played on it’s own as a classical piece here at around 5.05 and lasts for over a minute
I would absolutely love to get sheetmusic for this so I can play it on piano, of course I would be embarrassed if the music was just created for Sherlock Holmes though…
Thank you for help!
