With the household split up between Escorial, Malibu, Chicago and Boston I suspect that Mark will continue to employ multiple narrators depending on where the story takes us. With the digs in New York, and also in Hawaii, not to mention Wades Virginia estate, there is no shortage of locales.
I wonder if Wades little brother is going to be stuck in California while Wade moves to Boston?
The story has a target rich environment of potential story lines, all seemingly carefully set up by our cunning author and I for one am ready for wherever it leads us.
