The heavy rain fell hard against the old stone mansion. Inside the study a body lay sprawled across the floor. Blood dripped slowly from a fatal wound in the chest. The window stood open with curtains blowing in the wind. No guests heard any screams during the entire evening party. Detective Jones stepped into the room wearing a grave expression.
