Rain hammered the windows of Blackwood Manor throughout the night. Detective Eleanor Vance arrived before dawn to inspect the scene. Lord Blackwood lay dead beside his overturned mahogany writing desk. A silver dagger protruded grotesquely from his silk dressing gown. Blood had pooled beneath him across the expensive Persian rug. Seven guests remained locked inside the library down the hall. Each one claimed innocence while avoiding every other guilty glance. Outside the storm had severed telephone lines and roads completely. Eleanor knelt carefully and noticed something clenched within his fist. It was a torn photograph showing everyone here last summer. One face had been deliberately scratched away with violent force.
