Giving the room a quick once over, you don't find anything that seems important. From the papers that you do find, it's certain that this is not a doctors office. You try the phone on the desk but there's no dial tone. The bulletin board behind the desk would make a good target to take a practice shot, so you prop your flashlight up on the phone to light it up. You want to see if the sterno arrow will work, so you fire one up and shoot it at one of the papers on the board. Hitting the paper dead on from across the room, you see flaming sterno splatter, catching everything it touches on fire. You run over and grab your arrow and blow it out, then try to put out the board and floor. You grab the desk pad and hold it over the the burning area of the bulletin board, snuffing out the flames. With your feet, you manage to put out the small fires on the floor from the splattered sterno. The room now smells like fire and is sure to attract attention but you know that the arrows will work. Do you want to try and get the vent open before someone comes, go into another room and hope it also has a vent, or do something else?
