Emotionally devastated, Philip succumbs to bouts of fever and delirium, but Rachel nurses him back to health. In his fever, Philip imagines a wedding with Rachel, and wakes up three weeks later convinced they are married, and surprised to hear from the servants that she intends to move back to Florence. Before she leaves, Philip becomes convinced that Rachel is attempting to poison him and that she indeed murdered Ambrose. So great is his anger toward Rachel that he neglects to warn her about a foot bridge in need of repair at the edge of the estate. Instead, Philip and his friend Louise secretly rummage through Rachel's room for a letter from Rainaldi, assuming it will incriminate Rachel. Instead, upon discovering and reading the letter, they find out that Rainaldi merely discussed Rachel's affections for Philip and suggests she take Philip with him when visiting Florence. In the meantime, Philip finds Rachel has indeed suffered a fatal accident while crossing the unrepaired foot-bridge. With her last words, she asks Philip why he did not warn her of the danger. She then dies, leaving Philip to wonder for the rest of his life about his own implicit guilt as to the death of the innocent Rachel.
