They moved nearer to the open window, looking into the brilliantly lit ballroom, already filled with gaily chattering people. On a slightly raised platform at one end of the room the host and hostess were receiving their guests. The brother and sister were singularly unlike. Sir Aubrey Mayo was very tall and thin, the pallor of his face accentuated by the blackness of his smoothly brushed hair and heavy black moustache. His attitude was a mixture of well-bred courtesy and languid boredom. He seemed too tired even to keep the single eye-glass that he wore in position, for it dropped continually. By contrast the girl at his side appeared vividly alive. She was only of medium height and very slender, standing erect with the easy, vigorous carriage of an athletic boy, her small head poised proudly. Her scornful mouth and firm chin showed plainly an obstinate determination, and her deep blue eyes were unusually clear and steady. The long, curling black lashes that shaded her eyes and the dark eyebrows were a foil to the thick crop of loose, red-gold curls that she wore short, clubbed about her ears.

"The result is worth seeing," said the American admiringly, referring to his companion's last remark.

A third and younger man joined them.

"Hallo, Arbuthnot. You're late. The divinity is ten deep in would-be partners already."

A dull red crept into the young man's face, and he jerked his head angrily.

"I got waylaid by Lady Conway—poisonous old woman! She had a great deal to say on the subject of Miss Mayo and her trip. She ought to be gagged. I thought she was going on talking all night, so I fairly bolted in the end. All the same, I agree with her on one point. Why can't that lazy ass Mayo go with his sister?"

Nobody seemed to be able to give an answer. The band had begun playing, and the floor was covered with laughing, talking couples.

Sir Aubrey Mayo had moved away, and his sister was left standing with several men, who waited, programme in hand, but she waved them away with a little smile and a resolute shake of her head.

"Things seem to be getting a hustle on," said the American.

"Are you going to try your luck?" asked the elder of the two
Englishmen.
