A cold autumn rain lashed against the tall library windows. His worn trench coat dripped water onto the Persian carpet. The master of this grand house was now entirely dead. A single dark stain bloomed across his crisp white shirt. His family stood huddled by the doorway, faces pale with shock. A grandfather clock ticked loudly, each second a heavy accusation. An overturned wine glass had bled red onto the carpet.
