"What do you want to know?" Aide spoke gruffly. "Get your questions over with."
"Who is the mole?" Catherine was the first to speak. "Who did you contact when you infiltrated this place?"
"A mole? You mean a traitor within the Shadow Hand?" answered Aide. "I'm sure there is one, but I don't know who it is. I'm nominally in charge of this operation, but the person actually in charge of coordination and arrangements isn't me—it's Ovis. As for who the mole is, only he knows. However, I have met several times the person who's been taking care of our living arrangements and guiding us around here; they're a thief known as 'nimble fingers', supposedly one of the seven captains under Suspicion. Perhaps the traitor is Suspicion."
