There's always a lot of speculation here about the answers to questions which we really can't answer with certainty since we are not the authors of the screenplay or book. That, of course, is one of the things that makes these boards so much fun.

But...if you could have one question answered definitively by either Coppolla or Puzo (RIP), what would that question be?

Mine, of course, would be "Who killed the assasins in Tahoe after the attempt on Michael's life?".

Other suggestions, to get you started...

--What was Fredo's exact role in the assasination attempt?
--Exactly how many New York families were there?
--What did Clemenza really die from?

Remember, no answers on this thread. Only questions.
