The old Blackwood Manor stood silhouetted against a bruised sky, its shutters rattling as wind howled through the midnight hours. Detective Amelia Vance arrived at the estate, her trench coat soaked, eyes scanning looming entrance for any signs of danger. The heavy oak doors creaked open, revealing a lit foyer where a chandelier flickered ominously above the cold marble floor. Suddenly, a scream shattered the silence, prompting Amelia to sprint toward the source, her heart pounding like a frantic drum. In the study, the body of the patriarch lay crumpled on the Persian rug, eyes frozen in a horrified stare. A rain began to patter against the windows, mingling with the scent of iron as detective Vance inspected the scene. Nearby, a shattered whiskey glass glimmered under the lamp, a clue that the victim had struggled before the fatal blow. The butler, trembling, claimed he heard footsteps echoing down the corridor just minutes that night before the murder was discovered. Outside, the ancient oak tree groaned, its gnarled branches swaying like restless specters as the storm raged ever more violently. Detective Vance tucked a notebook into her pocket, determined to unravel the dark secrets hidden within these bloodstained walls tonight.
