“Very. I can’t understand it.”

“But he promised to go with us to the ball at Nice to-night!”

“Well, Miss Ranscomb, all I can think is that something—something very important must have detained him somewhere.”

Walter knew that his friend was suspected by the police, but dared not tell her the truth. Hugh’s disappearance had caused him considerable anxiety because, for aught he knew, he might already be arrested.

So Dorise, much perplexed, but resolving not to say to her mother that she had telephoned to the Palmiers, rejoined the Count in the hotel lounge, where they waited a further ten minutes. Then they entered the car and drove along to Nice.

There are few merrier gatherings in all Europe than the bal blanc. The Municipal Casino, at all times the center of revelry, of mild gambling, smart dresses and gay suppers, is on that night an amazing spectacle of black and white. The carnival colours—the two shades of colour chosen yearly by the International Fetes Committee—are abandoned, and only white is worn.

When the trio entered the fun was already in full swing. The gay crowd disguised by their masks and fancy costumes were revelling as happily as school children. A party of girls dressed as clowns were playing leap-frog. Another party were dancing in a great and ever-widening ring. Girls armed with jesters’ bladders were being carried high on the shoulders of their male acquaintances, and striking all and sundry as they passed, staid, elderly folk were performing grotesque antics for persons of their age. The very air of the Riviera seems to be exhilarating to both old and young, and the constant church-goers at home quickly become infected by the spirit of gaiety, and conduct themselves on the Continental Sabbath in a manner which would horribly disgust their particular vicar.

“Hugh must have been detained by something very unexpected, mother,” Dorise said. “He never disappoints us.”

“Oh, yes, he does. One night we were going to the Embassy Club—don’t you recollect it—and he never turned up.”

“Oh, well, mother. It was really excusable. His cousin arrived from New York quite unexpectedly upon some family business. He phoned to you and explained,” said the girl.
