Prologue to a non existant Book

Wrote this in creative writing, which in truth is not creative at all at my school. Thats a rant for a different time. Anyway....Here it is.

The night was blacker than a smokers lungs. Colder than the heart of a villain. And just as remorseless. A crisp breeze blew through the abandoned streets. Carrying his breathe away. And with it, the first brown leaves of autumn. The silence was ringing in his ears, enveloping him. If he didn't know better, he would believe he was the only human left in the abandoned metropolis. The crunch of a foot demolishing a leaf echoed, forlornly across the darkness. He stopped, fear clutched his heart. It overrode his brain with its dark tendrils of influence. With his new found fear came alertness. A responding crunch sounded in the distance. His muscles tensed, waiting to strike. He braced himself for the impending conflict. Seconds dripped by slowly in his dismal paranoia. After what seemed like years, he relaxed his muscles, and preceded to his destination. It was an echo, it had to be. He repeated that mantra in his mind, locked into the insanity that is fear, so busy soothing his mind, he failed to hear the stealthy footfalls his silent assailant.
