A shimmering image, like heat rising off a summer road, projected from the nut. The villagers, huddled in the shrine behind her, gasped. They saw the ghostly outline of the river, and superimposed over it, a series of small, round stones—not placed randomly, but in a spiraling pattern, like the grooves on the walnut's own shell.
