You pay the woman (deduct 3 Gold Crowns) and she hands you a key on which is stamped the number 4. Then she points to a corridor on the ground floor which leads to your room at the rear of the building. As you are about to insert the key into the lock, you hear a suspicious noise coming from inside your room. Silently you unsheathe your weapon, unlock the door, and then fling it wide open.
