Hidden lair!

I was leaving the school one day when I noticed a little trapdoor in the floor. I was surprised and curious as to what might be in there. I was also scared because there might be dead bodies in there. But me being adventurous, I decided to go down in there because I didn't have to catch a bus home. When I opened the door, there was a dusty old staircase made of wood. When I stepped onto the first step, it made a loud CREAK! After that, I was hesitant because I didn't want to get caught. After going down about 10-15 stairs, I was finally at the bottom. It was a cold cement floor. When I looked up, I noticed that there was a small card table and all the teachers were sitting there playing poker.
