Rain hammered the glass while Detective Mara Voss studied the library where Sir Julian Vale lay dead beside his brandy. The candles still burned though midnight had passed and every guest insisted no one crossed the hall after the toast. A silver letter opener rested beside the fireplace polished bright as innocence yet missing from its velvet case upstairs tonight. Mara noticed mud on the carpet pearls near the curtain and a torn ticket stub trembling inside the victim's glove. Then the conservatory door clicked open revealing Lady Vale with wet shoes calm eyes and lipstick darker than blood tonight. Somewhere beyond the thunder a clock stopped breathing and the murderer smiled behind an honest familiar face inside the room.
