Cold rain tapped quietly against the tall stained glass window. Lord Harrington lay completely still across his dark mahogany desk. A silver dagger pierced the velvet fabric of his coat. Fresh blood dripped slowly onto the expensive Persian carpet below. The grandfather clock struck midnight with twelve heavy brass chimes. Detective Miller stepped inside and surveyed the locked study carefully. A single black feather rested beside the cold right hand. Nobody could explain how the cunning killer escaped the room.
