Clad in a Persian-Renaissance gown and a widow's tiara of white batiste, Mrs Thoroughfare, in all the ferment of a Marriage-Christening, left her chamber on vapoury autumn day and descending a few stairs, and climbing a few others, knocked a trifle brusquely at her son's wife's door.

He had started to stroke her, shivering, staring ahead, following with a blind man's hand the dip of her spine through the batiste.
