A vulture flapped and shifted on the iron roof and Wilson looked at Scobie. He looked without interest in obedience to a stranger’s direction, and it seemed to him that no particular interest attached to the squat grey-haired man walking alone up Bond Street. He couldn’t tell that this was one of those occasions a man never forgets: a small cicatrice had been made on the memory, a wound that would ache whenever certain things combined — the taste of gin at midday, the smell of flowers under a balcony, the clang of corrugated iron, an ugly bird flopping from perch to perch.
