The plan had been of admirable simplicity and, as one would have thought, fool-proof. The garden, which measured five hundred by a thousand yards, was edged by a rectangular riding-path, which in turn was framed in a waterway. Sophie, Sophie Charlotte, and Caroline were to set out from Herrenhausen Palace, which rose up above the northern end, and execute a brisk lap around the path. Leibniz would do his best to keep up with them. The exercise would bring color to Caroline’s cheeks, which normally looked as if they had been sculpted out of library paste. Just before they completed the circuit, they would dodge in to the maze, where they would bump into young George Augustus. He and Caroline would "wander off" and "get lost" in the maze together—though of course Sophie and Sophie Charlotte would never be more than two yards from them, hovering like wasps on the other side of a thin screen of hedge, jabbing away whenever they perceived an opening. At any rate, through some winsome union of George’s level-headedness and Caroline’s cleverness, they would escape from the maze together and part company on blushing terms.
