The body lay crumpled beneath the old oak tree outside. Detective Harris knelt down and studied the victim's pale face. Rain had washed away most of the evidence by dawn. A single red rose rested gently on the woman's chest. No one in this quiet town expected something so terrible. The call had come in just after three this morning. Harris recognized the woman but chose not to say anything. Her name was Margaret Cole, the mayor's wife, no less. This case would tear the entire community apart, he knew. He pulled on latex gloves and examined her cold hands. Bruises circled her wrists like dark ribbons tied too tightly. She had fought hard against whoever did this to her. A young officer approached, holding a coffee and looking shaken. The neighbors reported hearing loud screams just after two thirty. Harris nodded slowly and turned his gaze back toward Margaret. Someone in this town was hiding a very dark secret. He would find them, no matter what the cost became.
