Short-ish Adventure

You scream "YES INDEED". He asks where 'the heck' they are. You hand him the bits of paper that the guard dropped, and he smiles lightly. "Congratulations, you do indeed haves the files." He awards you the rank of "file bringer". You then live the rest of your days delivering him files dropped by guards. One day he catches you just taking them from someone, and knowing that you have betrayed him, he sends you to the dungeon. You then have to find a way out. There's a gaping hole in the wall that you could easily escape through, and a key on the floor that you can unlock the door with.
