Detective Miller arrived at Thornwood Manor as the old clock struck twelve midnight, finding the study window shattered and bloodied. Inside the room, Lord Ashworth lay slumped across his writing desk, a silver letter opener buried deep in his neck. Rain hammered against the tall windows while lightning illuminated scattered papers, an overturned brandy glass, and strange muddy footprints nearby. The housekeeper discovered the body at half past eleven, screaming so loudly that the gardeners came running from the stables. Miller noticed something odd immediately: the desk drawers had been searched carefully, yet nothing appeared to be missing from them. On the floor beside the body rested a torn photograph showing five faces, but one figure had been cut away. Upstairs, the manor's guests slept peacefully in their rooms, each one claiming later they heard nothing unusual during that night. Miller pocketed the photograph, glanced once more at the dead man's frozen expression, and wondered who among them was lying.
