“’You’re sure she doesn’t know?’ said Georgie.

‘Antonia? About us? Certain.’

Georgie was silent for a moment and then said, ‘Good.’ That curt ‘Good’ was characteristic of her, typical of a toughness which had, to my mind, more to do with honesty than with ruthlessness. I liked the dry way in which she accepted our relationship. Only with a person so eminently sensible could I have deceived my wife.”
