Thunder rattled the stained glass windows of the grand library as Lord Blackwood took his very final, gasping breath alone. Red wine spilled across the antique Persian rug, mixing slowly with dark crimson blood pooling from a deep chest wound. The grandfather clock chimed midnight while an ornate silver dagger gleamed silently beside the fallen patriarch upon the oak floor. Footsteps echoed down the cold marble hallway, stopping abruptly outside the heavy oak door before the brass handle slowly turned. Detective Miller stepped inside with a smoking pipe, realizing immediately that every guest trapped within the manor had a motive.
