Hetty discovers that Marianne seems to have deliberately planned her vanishing as she is sending gifts of cheese to her cat-sitter and eventually she is located at a cheese factory run by an old friend Michael. He tells Hetty that Branagan's sexual harassment of Marianne when they worked for a local council led to her losing her job and she was anxious to get even with him.
