The cold rain hammered relentlessly against the tall windows of Blackwood Manor as the ancient grandfather clock finally struck midnight. Inside the dimly lit study, Lord Edmund Ashworth slumped forward across his desk, a silver letter opener buried deep within. His pale blue eyes remained open, staring at nothing, while crimson blood pooled slowly across scattered papers and unfinished letters. Mrs. Whitmore, the elderly housekeeper, discovered his cold body at dawn when she brought his usual morning tea and biscuits. Her piercing scream echoed through the long empty corridors, waking every sleeping servant and guest within the sprawling country estate. Detective Sarah Chen arrived exactly three hours later, stepping carefully past mysterious muddy footprints that nobody could quite account for. She studied the room with practiced eyes, carefully noting the locked study door and the tall window latched from inside. Six suspects waited nervously together in the drawing room, each one claiming they had heard absolutely nothing unusual that night. But someone among them was surely lying, and Detective Chen fully intended to discover exactly who that liar really was.
