The storm raged against Blackwood Manor’s ancient stone walls. Eleanor Ashworth lay dead upon the library’s Persian rug. A single emerald brooch glittered beside her cooling hand. Thunder rattled the stained-glass window depicting her family crest. Detective Cora Hale stepped carefully around the overturned armchair. She noted the open secret compartment in the mahogany desk. The coroner whispered, “No obvious wounds, no signs of struggle.” A grandfather clock chimed midnight, its pendulum swinging unnaturally fast. Cora’s eyes scanned the bookshelves, missing one leather-bound volume. Someone in this house knew exactly how Eleanor Ashworth died.
