Rain hammered the cobblestones outside the manor's heavy stormy doors. Inside, a crystal chandelier flickered, casting uneasy shadows on guests. Detective Marlowe arrived, his coat soaked, eyes scanning silently still. The host, Lady Whitfield, greeted him with forced, trembling smile. Before dinner, a scream shattered calm; a body lay uncovered. Marlowe knelt, examining the crimson stain spreading across polished floor. Whispers rose, accusing shadows; the night promised deadly revelations ahead.
