Again, I heard something behind me. Such a small noise, barely perceptible. A rat? I narrowed my eyes, refusing to give in to my paranoia as I resolutely continued down the street. There it was again, more distinct this time. A footstep. I looked over my shoulder, but there was no one there. Taking a deep breath, I did not linger. I walked a long way, almost to my building, without hearing another sound. Then it was right behind me again, coming fast this time. It was so close I could hear its breathing. I whipped around, drawing the slender blade from my walking stick, just in time to see a shadow flicker into the alley. I felt strangely triumphant. I wasn't a complete nutter.
