The grand chandelier flickered once, then went completely dark forever. Inspector Morse stood quietly beside the body of Eleanor Whitmore. Blood pooled silently on the Persian rug near the window. Three guests stood frozen in the doorway staring without speaking. Rain lashed hard against the glass of the old manor. No one had left the house since midnight last night. The dagger lay gleaming on the victim's white silk dress. Everyone in the room had a reason to hate her. A single violin string snapped somewhere upstairs in the dark. Justice would demand answers before the bright sun rose again.
