Heavy rain battered the tall gothic windows while Detective Miller carefully examined the lifeless body sprawled across the Persian rug. Lord Blackwood still clutched a shattered crystal glass, though not a single drop of red wine stained the expensive carpet. Instead, a faint scent of bitter almonds lingered near his pale lips, suggesting someone had poisoned his final evening drink. The heavy oak doors had been bolted firmly from the inside, leaving no obvious escape route for a clever killer. Miller stood up slowly, suddenly noticing fresh muddy footprints leading directly toward the massive mahogany bookcase beside the cold fireplace. Tonight, all six dinner guests remained trapped downstairs, and one of those smiling aristocrats was hiding a very deadly secret.
