Lydia Cole was a ghost, a wraith. Expertly, stealthily, she moved through the shadows, her movements precise and precise. She had been stalking Agent Reid for over three weeks now, since learning of her late sister's supposed involvement in a case that had brought him to St. Louis. She had followed him to coffee shops, the gym, and even his home. And tonight, she was going to take her revenge. She had done her research and discovered that Agent Reid lived in an isolated area on the outskirts of town, with no neighbors and no one to see her coming. She had purchased a gun and had carefully studied the layout of the house. She knew exactly what she had to do. Lydia crouched in the bushes on the edge of the property, her hands shaking slightly. Her heart raced as she watched the house and waited for her chance. The moments seemed to stretch for eternity until finally, the lights went out and the house was enveloped in darkness. Taking a deep breath, Sarah silently made her way across the lawn, her gun clenched tightly in her hand. The back door of the house opened without a sound as Sarah crept inside. She held her breath as she scanned the room. Nothing stirred. No one was home. Quietly, she made her way up the stairs, her footsteps light and silent. She kept her gun raised, ready for anything that might happen. She paused for a moment at the top of the stairs, steeling herself for what was to come. And then she walked into the bedroom. Agent Reid lay sleeping in his bed, unaware of her presence. Sarah raised her gun and pointed it directly at him. She knew that this was the moment of truth. This was her chance to take her revenge and find justice for her late sister.
