Toby was a person who got continually slapped on the back—a lovable habit, but one which no amount of diplomacy or thread-spinning will produce. To slap Jack on the back, for instance, must always, from his earliest years, have been an impossibility. This was lucky, for he would have resented it. That nobody ever quarrelled with either of them appears at first sight a point in common; in reality it illustrates their dissimilarity. It was dangerous to quarrel with Jack; it was blankly impossible to quarrel with Toby. You dare not try it with the one; it was useless to try it with the other.
At the present moment his sister-in-law was trying her utmost to do so, and failing pitiably. Kit was not accustomed to fail or to be pitiable, and it irritated her.
"You have no sense, Toby," she was saying. "You cannot see, or you will not, where your interest lies—yes, and your duty, too."
Now, when Kit talked about duty Toby always smiled. When he smiled his eyes wrinkled up till they closed, and he showed a row of strong, clean, useful teeth. Strength, cleanliness, and utility, in fact, were his most salient features.
Kit leaned back in her chair, waiting for his answer, for Toby got confused unless you gave him time. They were sitting in the tented balcony of the Hungarian Embassy, and from within came the rhythm of dance music and a delicious murmur of voices. It was the evening of the day of the bazaar, and Kit felt that she had earned her ball. The night was hot, and as she attempted the hopeless task of quarrelling with Toby she fanned herself, partly, no doubt, for the sake of the current of air, but to a psychologist, judging by her face, not without the intention of fanning the embers of her wrath. She had sat out this dance with him on purpose, and she was beginning to think that she was wasting her time.
Toby's smile broadened.
"When did you last do your duty, Kit?" he asked.
"My duty?" said Kit sharply. "We are talking about yours."
"And my duty is——"
"Not to go to that vulgar, stupid music-hall to-morrow night with that loutish friend of yours from Oxford, but to dine with us, and meet Miss Murchison. You seem to forget that Jack is your elder brother."
