Story Premise #13: Tweening

A pirate takes a lighthouse family hostage.  Their island is deserted and their only contact with the outside world is a supply boat that arrives every other month.   The pirate bosses everyone around and rains blows down on the head of anyone not doing his bidding. The family falls in line with the pirate's dominating authority, but the tween twins turn out to be formidable foes. 

After a month of the pirate having his way with everybody, the pirate gets a jolt of surprise when a second tween appears as he's about to torture the first.  Using his own oft used line, "This will be quick and relatively painless," the avenging tween gleefully shoots the pirate through the heart with his blunderbuss.   The girls laugh as his body sails from the top of lighthouse to the jagged rocks below.
