The woods are dark, and Combeferre doesn't know where to turn. He suspects Joly doesn't, either.

"Look!" Combeferre points. There's a triangle-shaped light floating in front of them. He takes a step, and another, and the light moves on ahead.

He turns to Joly, drawing a deep, excited breath. "It's shaped like a delta. Didn't you say that was how the Labyrinth was marked? This must be the way."
