PRINCESS W ILHELMINA C AROLINE of Brandenburg-Ansbach had been sending letters to Eliza almost every week since the summer of 1689, which was when they had last seen each other. Caroline had been six years old then. Now she was almost eleven. The handwriting, and the contents of her letters, had changed accordingly. Yet as Eliza stood on the deck of her Zille —the slim, hundred-foot-long river-barge she had chartered in Hamburg—and scanned the green banks of the Elbe, she was looking for the young mother and the little girl she had bid farewell to in the Hague five years earlier. There was no helping it. To a child, nothing seemed more stupid in adults than their inability to come to grips with the fact that people grew. Unfathomably moronic seemed the aunt or grandpapa who exclaimed "You have grown!" at each reunion. Eliza knew this as well as anyone who has ever been a child. And yet she was ambushed by the two women on the quay. They had been waving to her as the Zille drew near, and she had paid no more notice to them than to the cattle grazing in the undulating fields that rose up from the river’s edge.
