The parts all go together somehow, but you can’t always see it.  Or, sometimes things fit together better when you do something with them you shouldn’t.  The tension is as basic as the song that Bob used to sing on Sesame Street – “One of these things just doesn’t belong.”  Often I seem to be the thing that doesn’t belong.  Maybe that is why I see things from this point of view.  It’s actually better if everything doesn’t quite fit.  That is how life really works.  Plus, if the clues are too subtle and well hidden, no one will find the treasure, and what is the point of that?
