Look for a key

You decide there must be a key somewhere and you guess it's in this room. You make your way to the table that has the stakes on it. You noticed before that this table wasn't really a table but more of a counter because underneath were cabinets. You pull off the cloth along with the stakes and they clatter to the floor. You open each cabinet and look through each thoroughly but you find no key. You leave everything on the ground and walk to the table with holy water on it. You pick up a dark colored bottle and smash it. You do the same with the rest until three remain. You choose a dark green bottle and throw it on the ground. Glass flies and scatters among the shards already on the floor and your eye catches something gold slid across the floor. You dive after it and stop it before it slides under the cabinets and out of your reach. You grab the key and the last two bottles of water and slide the key into the lock. It pops open and you push the door and walk inside. Go to Door B2 (part two)
