Rain hammered against the tall glass windows of the estate. Lord Harrington sat slouched within his favorite leather armchair now. A crimson pool expanded steadily across the expensive Persian rug. The grandfather clock chimed midnight as shadows danced around him. Detective Miller quietly pushed open the heavy wooden library door. He smelled fresh gunpowder mixed with the bitter metallic blood. No weapon remained near the corpse resting upon the seat. The murderer had escaped through the garden during the storm. Only nine suspects remained inside the grand mansion tonight now. Miller picked up a single white glove from the floor.
