Standing here, as immune to the cold as a marble statue, gazing towards Charlotte Street, towards a foreshortened jumble of facades, scaffolding and pitched roofs, Henry thinks the city is a success, a brilliant invention, a biological masterpiece - millions teeming around the accumulated and layered achievements of the centuries, as though around a coral reef, sleeping, working, entertaining themselves, harmonious for the most part, nearly everyone wanting it to work. And the Perownes' own corner, a triumph of congruent proportion; the perfect square laid out by John Adam enclosing a perfect circle of garden - an eighteenth century dream bathed and embraced by modernity, by street light from above, and from below by fibre-optic cables, and cool fresh water coursing down pipes, and sewage borne away in an instant of forgetting.
An habitual observer of his own moods, he wonders about this sustained, distorting euphoria.
