Group of spies, say

NEST

Think of where covert operatives might gather—like birds in a hidden spot.

This clue plays on the double meaning of "nest." While it literally refers to a group of animals like birds, here it hints at a "group of spies" because spies are sometimes called "agents," and a group of agents could be a "nest" in a figurative sense. The word "say" signals that it’s a playful interpretation rather than a strict definition. Think of it like a spy "network" but with a nature-themed twist.
