The ship spots a British whaler at the island of Annamooka in Tonga. Wainright, captain of "Daisy", tells Aubrey about the situation on Moahu. There is a war between Kalahua in the north and Puolani in the south, with the northern chief being supported by the armed privateer "Franklin", sailing under the American flag, owned by Jean Dutourd of Louisiana, and Britain is at war with America. The privateer has captured "Truelove", a British whaler. While the crew provisions "Surprise", Clarissa, who has received a black eye from Oakes, confesses to Maturin on their botanizing walk together about her being sexually abused as a young girl and later working as a bookkeeper and occasional prostitute at a brothel in Piccadilly. These experiences formed her sexual outlook, indifference to something that gives no pleasure. Maturin explains the jealousy of men to her. When she mentions that she saw an aristocratic acquaintance of the late turncoats Ledward and Wray at the brothel, Maturin realises that he is the highly placed traitor long sought by Sir Joseph Blaine and Maturin. He sends a coded letter to Blaine via Wainwright.
