The rain hammered against the foggy window of the study. Thick velvet curtains did little to muffle the ominous sound. A single oil lamp flickered, casting eerie shadows on the books. The room smelled of aged leather and faint traces of cedar. Outside, thunder rumbled in the distance like distant gunfire. Footsteps echoed down the grand staircase, sending a chill down my spine. The clock on the mantel chimed midnight with agonizing precision. A cold draft slithered beneath the heavy oak door silently. Every portrait on the walls seemed to watch my every move. Silence shattered when a blood-curdling scream pierced the night.
