I am the qin player at Prince Yong's manor. Fourth Master allows me into the main hall to play, but never gives me a second glance.
He thinks all I can play is "High Mountains and Flowing Water," and that I know nothing of schemes or warfare. Until that night, when I lifted the bottom panel of my qin case and pulled out a hidden guard token. As Fourth Master was captured, I finally whispered to him, "Does Your Highness know why His Majesty loves 'Guangling Melody' above all others?"
The instant his pupils contracted, I cut through the ropes binding him.
