The body lay crumpled near the empty fireplace. Rain lashed against the mansion's tall, dark windows. Lady Ashworth's scream echoed through the silent hall. A single playing card rested on the hardwood floor. It was the ace of spades, perfectly placed. Inspector Cross knelt beside the lifeless, cold form. No one noticed the glass with two fingerprints. Dinner had been served precisely one hour ago. Every guest wore shock like a tailored mask. The clock above the mantel stopped at ten.
