And, overlaying all, the cries of a gang of boys playing football on the steps below, a fast and demanding game whose main challenge was to prevent the ball going missing in one of the inaccessible walled gardens all around, or plunging precipitously down the entire length of the salita, 287 steps to the point where it crossed the broad curve of paved street looping up the hillside.

Most dramatic were the intermittent appearances of aircraft on their final approach to Capodichino, monstrously large, deafening and unpredictable apparitions, seemingly near enough to touch. And yet, despite everything, the terrace where they were sitting seemed an oasis of calm and stillness, a secluded refuge miraculously isolated from the stress and stridency of the city all around.

Calling it a terrace was a bit of an exaggeration, too. In reality it was merely a section of flat tarred roof extending around two sides of a partial one-storey extension added illegally twenty years earlier to allow the original building to be converted into two apartments. The extension housed the kitchen and bathroom, while the bedroom and sitting room were on the floor below. There was a small eating area adjoining the kitchen, but now the summer had arrived Aurelio Zen preferred to take his meals outside, at an old marble-topped table in the shade of the green-and-white striped canvas awning.

The silence which still persisted between him and his guest was not at all awkward, and neither showed any urgency to break it. It was a large, comfortable silence, as unconstrained and embracing as the hazy sunlight which coated every surface around them, or the blowsy air which shifted caressingly to and fro. In the extreme distance, the ghostly outline of the peninsula of Sorrento could just be made out, like an old print bleached out by the sun.
