Rain hammered the conservatory roof while Evelyn Vale stood beside the locked piano watching blood slowly darken the Persian carpet. The guests below laughed over champagne unaware that silence above them had settled into the wallpaper like a second family. Detective Mara Wren arrived at midnight wearing winter's coat and carrying the calm of someone who notices doors before faces. On the mantel a clock ticked backward though every mirror reflected candles burning upright with one knife missing from service. Julian Vale lay smiling as if music had asked him a question only silence could answer beneath the locked roof. Mara opened the piano and found no weapon, only a note promising that everyone present would confess before dawn broke.
