Night Watch Manual

Secret community, high-paying vigil. The elevator always stops at the empty 13th floor, and the residents behave strangely, almost like ghosts. The ex left behind a blood-stained manual with a shocking warning: Beware of your own shadow and don't trust the person in the mirror. When I set foot in the restricted area, all the "residents" were waiting for me. It turns out that this manual is not a guide, but my only reliance in a narrow escape.
