Fog swirled through empty streets. Blood pooled beneath her body. Detective Morgan surveyed the scene. Rain fell from blackened skies. Her throat displayed vicious cuts. No weapon remained in sight. The alleyway smelled like death. Flashing lights illuminated her face. Pale skin reflected blue lights. Someone wanted this woman dead. Morgan crouched beside the victim. Her purse lay nearby, empty. No identification could be found. "Time of death?" Morgan asked. The coroner checked his watch. "Approximately three hours ago, sir." Morgan nodded, studying her hands. Manicured nails suggested money, status. Why here in this alley? What brought her down here? And who possessed such rage? The rain intensified its assault. Evidence washed away with time. Morgan sensed a difficult case. Another Jane Doe needed justice.
