Leaving the car, they walk along a path, where they see panes of slow glass facing a view of a loch.
They meet Mr Hagan, who is sitting on a low wall in front of his stone farmhouse and looking toward the house.
The narrator, sensing that Mrs Hagan, looking toward them from inside, is not aware of them, wonders whether she is blind; Selina remarks that her dress is out of fashion.
Hagan says how fine the view is from there; as he talks, the narrator, still looking at the house, wonders if the small boy is blind as well.
As the couple leaves with their purchase, Hagan sorrowfully tells them his wife and child were killed in a road accident six years previously.
