A Brass Key and Door 001

I pushed past a stack of books and stopped in front of the drawer's brass keyhole. It looked exactly like the keyhole of Door 001 in Doors. I checked both sides, alert for any flickering light, then reached out to touch the cold metal edge. Right beside it, half-buried under paperclips, was an antique brass key. I picked it up with both hands, lined it up, and turned it until a soft, heavy click echoed through the dark room. Next door unlocked. No Rush in sight, but I kept my guard up.
