She smiled. "Oh, as for that, Mr. Wrandall, I think we can all trust you to cling pretty closely to your own level."
"Rather ambiguous, that," he remarked dubiously.
"She means you never get below it, Leslie," said Booth, enjoying himself.
"That's the one great principle in aeroplaning," said Wrandall, quick to recover. "Vivian says I'll break my neck some day, but admits it will be a heroic way of doing it. Much nobler than pitching out of an automobile or catapulting over a horse's head in Central Park." He paused for effect before venturing his next conclusion. "It must be ineffably sublime, being squashed—or is it squshed?—after a drop of a mile or two, isn't it?"
He looked to see Miss Castleton wince, and was somewhat dashed to find that she was looking out of the window, quite oblivious to the peril he was in figuratively for her special consideration.
Booth was acutely reminded that the term "prig" as applied to Leslie was a misnomer; he hated the thought of the other word, which reflectively he rhymed with "pad."
It occurred to him early in the course of this rather one-sided discussion that their hostess was making no effort to take part in it, whether from lack of interest or because of its frivolous nature he was, of course, unable to determine. Later, he was struck by the curious pallor of her face, and the lack-lustre expression of her eyes. She seldom removed her gaze from Wrandall's face, and yet there persisted in the observer's mind the rather uncanny impression that she did not hear a word her brother-in-law was saying. He, in turn, took to watching her covertly. At no time did her expression change. For reasons of his own, he did not attempt to draw her into the conversation, fascinated as he was by the study of that beautiful, emotionless face. Once he had the queer sensation of feeling, rather than seeing, a haunted look in her eyes, but he put it down to fancy on his part. Doubtless, he concluded, the face or voice or manner of her husband's brother recalled tragic memories from which she could not disengage herself. But undoubtedly there was something peculiar in the way she looked at Leslie through those dull, unblinking eyes. It was some time before Booth realised that she made but the slightest pretence of touching the food that was placed before her by the footman.
And Leslie babbled on in blissful ignorance of, not to say disregard for, this strange ghost at the feast, for, to Booth's mind, the ghost of Challis Wrandall was there.
Turning to Miss Castleton with a significant look in his eyes, meant to call her attention to Mrs. Wrandall, he was amazed to find that every vestige of colour had gone from the girl's face. She was listening to Wrandall and replying in monosyllables, but that she was aware of the other woman's abstraction was not for an instant to be doubted. Suddenly, after a quick glance at Sara's face, she looked squarely into Booth's eyes, and he saw in hers an expression of actual concern, if not alarm.
Leslie was in the middle of a sentence when Sara laughed aloud, without excuse or reason. The next instant she was looking from one to the other in a dazed sort of way, as if coining out of a dream.
