The rain hammered the ancient manor's windows all through night. Inside, the fire crackled low, casting long dancing shadows everywhere. A clock struck midnight, and then a woman's scream echoed. The butler found Lord Ashworth dead in his locked study. A single playing card lay upon the cold marble floor. The ace of spades, its edge stained with crimson red. Inspector Holmes arrived, his sharp eyes scanning every small detail. He knelt beside the body, touching the cold, still wrist. "This was no accident," he murmured, frowning at the card. The storm outside seemed to laugh at their grim discovery.
