The morning fog swallowed Blackthorn Manor before anyone noticed blood. Detective Mara Voss arrived shortly after the church bells stopped. Inside, the household waited beneath portraits of their stern ancestors. Nobody spoke when Mara entered the library and saw him. Lord Blackthorn lay beside the fireplace, his throat neatly cut. A silver chess piece rested between his cold, outstretched fingers. The white queen, Mara observed, though the board remained untouched. Lady Blackthorn stood nearby, wearing gloves despite the oppressive heat. She claimed her husband had retired alone after midnight yesterday. Yet two wineglasses stood on the desk, both freshly emptied. One bore a lipstick mark; the other held a key. Mara lifted the glass, revealing an engraving beneath its base. Her own name stared back, scratched deeply into the glass. Behind her, the front door slammed, and every servant flinched.
