When the son of Louis XIII had moved his court to Versailles, the son of Antoine Rossignol—who had inherited Antoine’s château, his knowledge of cryptanalysis, and his responsibilities—had found himself exiled. He had not moved, but the center of power had, and Juvisy had all of a sudden begun to seem like a remote outpost. Another man might have sold the place at a loss, and built a new château somewhere around Versailles. But Bonaventure Rossignol had been content to remain in the old place. His work did not require continual attendance at Court. If anything, the distance, and the peace and quiet that came with it, made him more productive. Le Roi had ratified the younger Rossignol’s decision by coming to visit him at Juvisy from time to time. In its smallness, its seclusion, and the prim perfection of its walled garden, the château at Juvisy seemed to Eliza like a perfect little kingdom of secrets, with Bon-bon its king, and Eliza its queen, or at least concubine.
