"Once on a dark winter's day when the yellow fog hung so thick and heavy in the streets of London that the lamps were lighted and the shop windows blazed with gas as they do at night an odd-looking little girl sat in a cab with her father and was driven rather slowly through the big thoroughfares. She sat with her feet tucked under her and leaned against her father who held her in his arm as she stared out of the window at the passing people with a queer old-fashioned thoughtfulness in her big eyes."
