The clock struck twelve midnight. Rain hammered the old manor. Nobody heard the sharp scream. Margaret lay on cold marble. Her eyes stared at nothing. Blood pooled around her head. The candles flickered and died. Darkness swallowed the grand hall. Someone had locked every door. The guests slept upstairs peacefully. Or so the killer thought. Detective Cole found her first. He knelt beside her body. Something felt terribly wrong here. No weapon lay in sight. Yet Margaret was surely dead. Cole reached for his radio. Static crackled through the silence. He whispered one quiet word. That word was simply murder.
