In the year 1643, a violent storm in the South Pacific leaves Roberto della Griva shipwrecked—on a ship. Swept from the Amaryllis, he has managed to pull himself aboard the Daphne, anchored in the bay of a beautiful island. The ship is fully provisioned, he discovers, but the crew is missing. As Roberto explores the different cabinets in the hold, he looks back on various episodes from his life: Ferrante, his imaginary evil brother; the siege of Casale, that meaningless chess move in the Thirty Years' War in which he lost his father and his illusions; and the lessons given him on Reasons of State, fencing, the writing of love letters, and blasphemy.
