The old clock struck midnight within the darkened manor house. Jasper Thorne’s lifeless body sprawled across the Persian rug’s red threads. A single crystal glass of port sat undisturbed and still. Ten guests stood frozen in the flickering, fire-lit grand room. Each face held a secret, their eyes reflecting only shadows. Detective Inspector Albright closed his leather notebook with a soft snap. “No one will leave this house until I find everything.”
