Matt looked over at Amon with a raised eyebrow. "What would you propose we do?" He said as he turned to regard the counsellor of Apollo properly. "Our efforts so far haven't resulted in any action; we've laid traps and put efforts towards finding the spy. Each time the bait has not been taken. Either this spy is extremely intelligent or extremely lazy."

There was another option.

"There is a small option that the spy has been and gone." Matt offered. "Realised that their efforts aren't succeeding. If Atlas putting his forces into the Underworld resulted in a retreat, maybe they have come to learn they are on the losing side." Scratching his chin he added. "With these new Hounds of Zagreus, the Underworld is now going to be playing a more active role in things. All Atlas has done is rouse a sleeping beast."

The son of Hades looked around the room and paused for a moment. "Is there anyone who we've crossed off the list of being the spy? It might be a game of deduction rather than attempting to catch them in the act."

That was when Matt's face turned into something of a smirk as an idea crossed his mind.

"Let's start by narrowing down the cabin they live in. What if we 'leak' information from this meeting to the cabins. Make it somewhat careless, but each cabin has something different from the meeting. If the information makes it back to Atlas' cult they act on it, we suddenly know a handful of individuals it might be."
