Lightning cracked above the ancient manor’s silent, foreboding stone walls. Footsteps echoed through the deserted hall, shadows dancing on walls. Detective Sinclair arrived moments too late, finding crimson stains everywhere. A lifeless body lay sprawled across the ornate Persian rug. Candles flickered ominously, casting monstrous silhouettes upon anxious visitors faces. A chilling wind whispered secrets through cracked, broken, ancient windowpanes. The distant clock tolled midnight, affirming that evil awakening begins.
