'Tis a Puzzlement

Nothing to do with the King and I from where I stole the quote, but a jigsaw puzzlement. 

The jigsaw has 1000 pieces and took many hours to complete.  I had no guiding picture to work from.  Just a bag of 1000 pieces.  It was meant to be a mystery puzzle with a twist.  Completing the jigsaw was supposed to provide the final clue to 'Murder on the Hindenburg'. 

Unfortunately I don't have a clue because the book with the story relating to the picture was not in the box. The picture on the box had absolutely nothing relating to the picture in the puzzle.  At least I completed the puzzle and there were no missing pieces.  I will never know who was murdered and who was murderer. 'Ttis a puzzlement.
