Rain lashed violently against the grand stained glass windows of Blackwood Manor while Detective Vance stared at the lifeless body. Lord Harrington lay sprawled across the rich Persian rug, an ornate silver letter opener protruding deeply from his bloody chest. A shattered grandfather clock in the dark corner was permanently frozen at precisely three minutes past the hour of midnight. Outside the locked study door, four anxious house guests waited silently, each harboring a dark secret that could prove fatal. Detective Vance knelt beside the victim, plucked a single white feather from the growing pool of blood, and smiled grimly.
