Richard Pavlicek made a great bridge site.

The mystery is this:
Is there a bridge hand where North/South can make a grandslam in any suit, but not even make 5NT?
he asks for solving a mystery and how close he came to a solution. He claims he first saw it in a newspaper.
I am also very interested in this task.
Does anyone know a solution or, better yet the deal Richard Pavlicek might have seen in the newspaper??
