I run in and snatch it off you, hiding myself in a secret basement, with all copies of the map to it, with no windows, doors, trapdoors, secret entrances, no keys, etc. I got in because I ran in the only door, ripped it off, and concreted it. The whole place is completely bomb, dynamite, hammer, ATTACK proof, and there is NO way in OR out, except for a smaaaaaall crack in the very thick cement for me to breathe.
MY STRING!
