The silver blade rested against the cold and marble floor. Blood pooled slowly around the velvet slippers of the countess. No one heard the muffled scream behind the heavy curtains. Rain lashed against the glass of the tall library windows. Detective Miller stepped inside and shook his damp woolen coat. He noticed the broken lock on the grand mahogany door. A single low lamp cast long shadows across the room. Silence hung heavy within the air like a thick shroud. The victim lay still beneath the portrait of her ancestor. Her empty eyes stared blindly at the ornate golden ceiling.
