The grand estate loomed under storm clouds heavy with unseen threats. Rain tapped against windows while shadows stretched across polished oak floors. A single candle flickered weakly, casting eerie light upon the portrait. The butler’s hands trembled slightly as he adjusted his immaculate black gloves. Footsteps echoed down the hall, though no living soul appeared there. The clock struck midnight, its chime swallowing the last guest’s nervous laugh. Blood seeped slowly from beneath the study’s locked mahogany door. Someone had silenced the master before he could reveal his secret. The detective’s boots clicked sharply against marble as he surveyed chaos. Every face in the room held guilt—or perfect, practiced innocence.
