★★★ Dazzling light crisscrossed the avenue on the way to the school. The blue of the sky had deepened, but not yet to the new season’s standard, and some haze still stuck to the sidewalk. The heat of the sun couldn’t overcome its loss of position in the sky, so midafternoon was merely tepid. After sundown, though, it was still too hot for a suit. The strong smell of garbage floated on the night air far downtown. From the 102nd floor, the unimpeded lights made the lines of Manhattan legible to the vanishing point.
