The rain fell steadily over Blackwood Manor that evening, shrouding its ancient towers in a thick gray veil of mist. Inside the great hall, twelve guests had gathered for the annual dinner, unaware that one of them would never leave. Lord Ashworth stood at the head of the long mahogany table, raising his crystal glass to greet his assembled guests. His voice carried across the room with warmth, though his eyes seemed distant, fixed upon some troubling thought beyond candlelight. Lady Ashworth smiled beside him, but her hands trembled slightly as she smoothed the folds of her black silk gown. A clock chimed ten times in the darkness, and somewhere above them, a door creaked open with an ominous groan. The guests paused their conversations, listening to the silence that followed, each one secretly wondering who had gone upstairs tonight. Nobody saw the shadow slip along the gallery above, moving with the quiet patience of someone who knew the house. By midnight, Lord Ashworth would be found dead in his study, a silver letter opener buried deep within his chest. The storm would trap everyone inside until morning, and every single guest at that table held a motive for murder.
