I spun around, chasing movement I saw from the corner of my eye. Nothing. I looked around. No one else on the street. Suddenly, the buildings seemed to loom up around me and lean in, blocking out the cold sunlight. I hastened my step, boot heels sounding loudly on the sidewalk. I looked as far as I could down each alley that I passed; they were full of dark spaces that could be concealing anything. The thought of all the unnatural eyes that must be watching me from windows and side streets gave me gooseflesh. Finally I started to run.
