The heavy rain hammered the windows of Blackwood Manor tonight. Inside, guests gathered beneath chandeliers for reading of the will. Lord Blackwood was absent, which everyone found very strange indeed. His lawyer, Finch, shuffled papers and avoided every curious gaze. A clock ticked while thunder rolled across the dark hills. Then the study door opened, and a maid screamed once. The blood stained carpet beneath the desk where Blackwood sat. The victim was not Lord Blackwood, but his younger brother. Detective Mara Voss arrived later, shaking rainwater from her coat. She studied the room and asked who found the body. No one answered; outside, the storm finally began to fade. Detective Voss knew this quiet manor now hid a killer.
