Rain hammered the old manor. Shadows clung to cracked windows. A lone lantern flickered weakly. Footsteps echoed through empty hallways. The steward sipped steaming coffee. A scream shattered midnight silence. The body lay sprawled motionlessly. Crimson stained the polished floor. Detective Marlow arrived, hat drenched. He surveyed the gruesome tableau. Whispers hinted hidden family secrets. The clock struck thirteen hours.
