Left

Shrugging you turn down the left corridor, looking at each door you pass for a sign indicating it belongs to the headmistress but seeing only numbers. Halfway down the corridor you're about to give up and turn back when you hear a murmur of voices and see a door ahead of you standing open a few inches. Thinking to ask for directions you push the door open a bit further and look into the room.

What you see makes you pause in surprise, your words dying in your mouth as you take in the scene.
