The servant waited for Master Cuan to close up shop, then led him quickly back to the castle.  In a short time, they were standing outside the door of the Captain's quarters.  The boy knocked quietly, and stepped back as the door slowly opened.  The Prince stood there, and quickly stepped out into the hall, closing the door behind him.  "Greetings, Master Cuan.  I'd like to thank you for coming on such short notice."
