Rain hashed the windows while the library clock stopped dead. Detective Mara Voss found Sir Edwin fallen beside the globe. A silver letter opener gleamed beneath his still open hand. The study smelled of smoke, almonds, and expensive secrets tonight. Every guest downstairs claimed the storm had trapped them inside. Yet muddy footprints crossed the terrace toward the maze beyond. Mara noted the victim's watch read eleven thirteen precisely tonight. Then the lights failed, and someone whispered her name twice.
