The ancient manor house loomed ominously against the stormy, starless sky, swallowed by the creeping, unnatural dread. Detective Miles Corbin’s trench coat dripped heavily as he stepped onto the crumbling porch, his keen eyes scanning everything. A trembling maid, Miss Abigail Periwinkle, clutched a fragile lace handkerchief, her face pale with unspeakable, chilling terror. She pointed a shaking finger towards the shadowed study, where a dark crimson stain marred the expensive Persian rug. Whispers of betrayal and dark secrets seemed to hang heavy in the air, promising sinister revelations soon. The grand grandfather clock in the hall chimed eleven, its mournful toll echoing like a death knell tonight.
