Rain polished the windows as midnight entered Blackwood Manor. Inspector Vale arrived before anyone discovered the locked library. Inside, Lord Blackwood slumped beside a dying fireplace alone. A crimson chess piece rested within his open palm. Every clock had stopped precisely at eleven minutes past. Yet fresh footprints crossed dust toward the sealed balcony. Vale counted six guests waiting beneath the chandelier downstairs. One smiled calmly, wearing mismatched shoes and muddy cuffs.
