The rain hammered against the window like impatient fingers tapping glass. No one expected the old mansion’s newest guest would be found dead. Clara sighed, clutching her teacup tighter as whispers filled the dim foyer. The butler’s polished shoes clicked sharply across the marble hallway floor. A cold draft slithered through the hallway, carrying an unfamiliar, bitter scent. The grandfather clock struck midnight with a gong that echoed through the house. Shadows stretched long across the walls, twisting like the thoughts in Clara’s mind. A single earring glinted on the floor near the grand staircase’s base. Clara’s breath hitched as she noticed the earring wasn’t hers. The estate’s lawyer cleared his throat, breaking the suffocating silence.
