On Monday morning, Jonathan drops Martha at St. Pancras for her train to Enderford. He watches her depart, pleased to see her emotional, and then drives back to Tooting to return to Amanda’s apartment, where he has been posing as a man undergoing medical treatment.

As he walks, Jonathan consciously adjusts his posture and demeanor to look older and frailer, crafting the image of someone exhausted by a multi-day hospital procedure. He enters Amanda’s flat projecting fatigue. Amanda, wrapped in a gray fleecy shawl, asks after his treatment and mentions failed calls. He delivers a detailed lie about intensive five-hour sessions without food, sunlight, or windows, and asks to go straight to bed.

Amanda responds with concern, saying she has prepared fresh sheets and offering tea. Jonathan declines and expresses deep gratitude for her support and for obtaining money for his supposed treatment. Amanda accepts this and sends him to rest.

Alone in the bedroom, Jonathan looks through photos from the Cotswolds getaway with Martha. He debates deleting them but lingers over images of their apparent happiness and his own vanity about aging well. Just as he is about to delete the photos, the doorbell rings.

Jonathan hears Amanda go to the door and recognizes the visitor’s voice: it is Tara, his wife, whom he has not heard for two weeks. The chapter ends on this reveal, implying an imminent confrontation at Amanda’s apartment.
