No time like the present. We may as well put our cards on the table now. “We know you have been secretly serving us Fantasia.” Noel stores away his pie and provides us with his undivided attention. “And what has lead you to that conclusion, I wonder.” “Lilly, if you would.” “Of course, Detective.” Lilly steps forward.
“Evidence number 1.” Lilly grabs the Severian's list of renowned alchemists. “We know this Fantasia was custom made. There are few people who would be capable of doing so. One of them being you, as you yourself have been an excelling member of the alchemist guild.”
“Evidence number 2.” Lilly swaps the lists, now presenting the one containing the ingredients. “The ingredients listed by the alchemists guild to be contained within the Fantasia mixture. Ingredients we have found to be within your possession.” I reveal both ingredients we uncovered.
“Evidence number 3.” Putting the second list back in her pocket she stares Noel in the eyes.
