One day she leaves a gift for Charles, a nude photograph that she took of him asleep in the laboratory after lovemaking, and he begins to shun her. When a fellow scientist visits, Charles claims sole credit for the technique she discovered. Angered by his rebuff and betrayal, Mary at first takes it out on Henry, but then decides to leave the island and return to London. On her way out, conspicuously dressed as a Jew once more, she presents to Mrs Cavendish at their dinner table the picture of her naked husband.
