Heavy rain battered the tall gothic windows of Blackwood Manor while thunder shook the ancient foundations beneath the plush carpet. Lord Alistair lay motionless upon the mahogany desk with a silver dagger protruding awkwardly from his tailored velvet smoking jacket. Detective Inspector Vance adjusted his damp trench coat and carefully examined the crimson pool spreading across the scattered financial documents. Every single door and window in the spacious study had been bolted securely from the inside before the fatal strike. Downstairs in the drawing room, five terrified guests waited nervously, knowing one among them was a ruthless and cunning killer. A faint scent of bitter almonds lingered in the air, suggesting the blade was not the only weapon used tonight.
