The rain hammered against the cracked windowpane like bullets from a distant war zone, masking the silence inside the room. Lord Blackwood lay sprawled across the Persian rug, blood pooling dark beneath his still, cold fingers near the shattered glass. A single playing card rested face up on his chest, the red king bleeding ink onto the crisp white shirt. Detective Miller stepped carefully over the threshold, his eyes scanning the cluttered study for any sign of the killer's escape. The grandfather clock in the corner chimed midnight, its metallic voice echoing through empty hallways like a sharp death knell. He noticed something glint near the window sill, forcing him to realize this grim scene held a secret more deadly.
