Charlie reads articles about Bronwyn and Timothy while waiting for Clara and Wynnie’s arrival. He wonders again why Bronwyn disappeared and where Callum acquired her notebook. The doorbell rings. Charlie is struck by Clara’s beauty when he greets her on the doorstep.

Charlie leads Clara and Wynnie into his parents’ palatial home. He has the maid, Moira, bring them tea and snacks before giving Clara Bronwyn’s satchel and letter. He then shows them Callum’s study and tells them about his mother, Pippa, who’s staying at his summer house in Cumbria. Clara and Wynnie share their plans for their London stay. Shortly thereafter, they say their goodbyes; Charlie reminds Clara that she can contact him if she needs anything.

Outside, the fog has thickened. Clara and Wynnie struggle to make it back to their rented room. A man bumps into them, almost knocking Wynnie into the river. Wynnie starts coughing and complains of a burning throat and eyes. Clara digs in her bag for Wynnie’s medicine but realizes that she forgot it. They race back as fast as they can. In a panic, Clara administers Wynnie’s medicine.
