It was a summer's evening in Sydney, and the north-east wind that comes down from New Guinea and the tropical islands over leagues of warm sea, brought on its wings a heavy depressing moisture.

Everyone who could manage it was out of town, either on the heights of Moss Vale or the Blue Mountains, escaping from the Inferno of Sydney.
