The fog rolled in softly over the silent town square tonight. An eerie breeze whispered secrets through the ancient, twisted trees quietly. Detective Morgan arrived promptly, eyes scanning the deserted, dim alleyway. A scream shattered the calm, echoing beneath the cold, gray sky. Late hour shadows revealed a figure sprawled on cold cobblestone. Blood pooled around the body, shining under the flickering streetlamp light. No witnesses appeared as Morgan kneeled, studying the victim's trembling hand. A single, blood-red flower lay clutched in her stiff fingers. Footsteps approached quietly, disturbing the surrounding darkness, whispering suspicion. Hence began the mystery that would threaten everyone’s calm and safety.
