You saw him standing there, motionless. In the dimly lit alleyway, he stood out - his tall, slender figure looking almost too perfect to be human. He wore a tailored black suit, and his face was obscured by a mask adorned with sinister markings and a pair of lenses that glowed red in the darkness, with his head turned in another direction. You suddenly feel a sense of unease - there was something about this man that made your heart race with fear.
