Beneath the crackling library fireplace’s dim glow, a crumpled body slumps against a shelf stacked with dusty old history books. A crumpled letter bearing no return address tumbles from the victim’s clenched fist when a sudden wind whips through windows. A shadowy figure watches from the hidden upper balcony before slipping a glinting knife back into a worn leather pouch.
