On the run

Standing up you look around the room, you are determined not to sit and wait for something to happen. You start to run your hands over the walls. You feel a small draft of air. Cupping your hands underneath the stone you find that it moves away easily. You take one last look around the room and pull yourself out, after about 5 minutes you manage to get out. You're surprised that no one has seen you. Dropping to the ground you move slowly making sure no one sees you. You reach the gates hiding behind a pillar you watch how people get in and out. Just as you have decided to try and find another way out, as this way is too hard you hear alarms ringing. 'Oh no', you know it's only a matter of time now.
