Onyx strode into the dreary, empty Burger King, the heels of her knee-high black boots making soft clicking sounds on the cracked, peeling linoleum floor. She had come to this deserted place in search of one thing: Her prized onyx ring, which had been given to her by her mother. It had managed to slip off her finger the last time she was here, just this morning. She'd noticed its disappearance only a quarter hour before, and had quickly retraced her path to the Burger King. She wanted it safely nestled on her fourth finger before nightfall, when the shadows were sure to get ahold of it. With a flip of her dark, magenta-streaked hair, she got down on her hands and knees and began to search every nook and cranny of the fast-food restaurant. Suddenly, she heard a thump behind her. Onyx's hand flew to the 9mm Glock at her waist. She slowly edged it out from under the thin black belt that was cinched around her flowy, dark magenta off-the-shoulder blouse, then swiveled around, bracing herself for a fight. There was no one there. Onyx's mind spun with thoughts. What was the mysterious thumping sound?
