"It is the roulette I want, not the opera," Mary heard herself say, as if some one else were speaking.

"Ah, Mademoiselle has her ticket of admission?"

She showed him her vestiaire ticket, and the servant of the Casino was too polite to smile, as he explained that something else was necessary before she would be allowed to enter the gambling-rooms. He pointed toward three swing-doors at the far end of the hall, to the left. Through two of these, people were going into a room beyond. Through the middle one they were coming out into the atrium; and as the big doors swung rapidly back and forth there were glimpses on the other side of a vast space full of rich yellow light.

"Those messieurs stationed there would stop Mademoiselle, seeing she was a stranger, and demand her ticket. It is better that she return to the bureau, a room opposite the vestiaire where she has left her cloak."

This was an anticlimax, after summoning courage for the plunge into battle; but Mary returned whence she had come, to take her place behind others who waited for tickets of admission. She listened intently to what passed, so that she might know what to do; but it was disconcerting when her turn came, to be asked for a visiting-card. The lately emancipated Sister Rose possessed no such thing, and expected to be sent away defeated. Yet a path out of the difficulty was quickly found by the alert, frock-coated, black-necktied official behind the long desk. This charming young woman, beautifully and expensively dressed, was not one who deserved to be discouraged from entering the Casino. All she need do was to give her full name and nationality, also her place of residence. Gladly she obeyed; and holding in her hand a carte du jour on which she had written her own name, at last she had the right of entrance.

There was still one more mistake to make, however, and she promptly made it, attempting to pass through the right-hand swing-door. But no! It was for season-ticket holders. She must go to the left. The middle door was for those coming out. A fat man, hurrying brusquely in before her, let the swing-door slam in her face. "Le joueur n'a ni politesse, ni sexe," was a proverb of the "Rooms" which Mary Grant had never heard, but would come to understand.

She was on the threshold of an enormous room, magnificently proportioned, hung with lustrous chandeliers, and divided by an archway into two sections. The farther part was much larger than that which she had entered, and more sumptuous in decoration; but the whole was flooded with a peculiar radiance which turned everything to gold. It was far mellower than the light of the atrium, or the splendid rooms of the hotel. It had actual colour like honey, or the pinky-golden skin of apricots. It was bright, yet the impression it made on the mind was of softness rather than brilliance; and the shining atmosphere of the room, instead of being clear, seemed charged with infinitesimal particles of floating gold, like motes in rays of sunshine. The tables, under darkly shaded, low-hanging lamps, gave the effect of sending a yellow smoke, like incense, up to the height of the great dazzling chandeliers. It was almost as if the hands of players in fingering gold pieces day after day, year after year for generations, had rubbed off minute flakes which hung like a golden haze in the air.

It appeared to Mary's eyes, taking in the whole and not dwelling upon details, that everything in the farther part of the vast domed room was of gold: different shades of gold; dark, old gold, the richer for being tarnished: bright, glittering, guinea gold: greenish gold, and gold of copper red.

No other colour could have been as appropriate here.

The air was not offensively dead, but it was langorously asleep. Many different perfumes haunted and weighed it down; but there was some underlying, distinctive odour which excited the nerves mysteriously, and sent the blood racing through the veins.
