Two levels down, I stepped off the stairs and followed my memory of the blueprints through a mesh of corridors until I was reasonably sure that the door to Kawahara's quarters was around the next corner. With my back to the wall, I slid up to the corner and waited, breathing shallowly. The proximity sense said there was someone at the door around the corner, possibly more than one person, and I picked up the faint tang of cigarette smoke. I dropped to my knees, checked my surroundings and then lowered my face to the ground. With one cheek brushing the pile of the carpet, I eased my head around the corner.
