Detective Mara Hall arrived at Blackwood Manor just before dawn. Rain hammered the cobblestones while thunder echoed across empty hills. Inside the library, Lord Edmund lay motionless beside overturned chair. A single candlestick glowed beside his cold, pale, lifeless hand. Mara noticed the window latch was broken from the inside. The guests gathered silently, each hiding fear behind polite smiles. Someone in this ancient house had wanted Edmund dead tonight.
