Derek led me down a corridor I hadn't explored before, past several closed classroom doors and what appeared to be storage areas. The hallway was quieter than the main sections of the school, with the kind of neglected feel that suggested it wasn't used regularly during normal school hours.
"In here," Derek said, stopping at a door marked with a faded sign that read "Science Lab B - Under Renovation." He produced a key from his pocket with the casual confidence of someone who'd done this many times before.
"How did you get a key?" I asked as he unlocked the door.
"You'd be amazed what people lose and forget to report missing," Derek replied, pushing the door open and gesturing for me to follow him inside.
