And a moment later Mademoiselle had pushed before her at the end of the croupier’s rake another pile of counters, while all those who had followed the remarkable woman’s play were also paid.

“Mademoiselle is in good form to-day,” remarked one ugly old Frenchwoman who had been a well-known figure at the tables for the past ten years, and who played carefully and lived by gambling. She was one of those queer, mysterious old creatures who enter the Rooms each morning as soon as they are open, secure the best seats, occupy them all the luncheon hour pretending to play, and then sell them to wealthy gamblers for a consideration—two or three louis—perhaps—and then at once go to their ease in their own obscure abode.

The public who go to Monte know little of its strange mysteries, or of the odd people who pick up livings there in all sorts of queer ways.

“Ah!” exclaimed a man who overheard her. “Mademoiselle has wonderful luck! She won seventy-five thousand francs at the Cercle Prive last night. She won en plein five times running. Dieu! Such luck! And it never causes her the slightest excitement.”

“The lady must be very rich!” remarked an American woman sitting next to the old Frenchwoman, and who knew French well.

“Rich! Of course! She must have won several million francs from the Administration. They don’t like to see her here. But I suppose her success attracts others to play. The gambling fever is as infectious as the influenza,” declared the old Frenchwoman. “Everyone tries to discover who she is, and where she came from five years ago. But nobody has yet found out. Even Monsieur Bernard, the chief of the Surveillance, does not know,” she went on in a whisper. “He is a friend of mine, and I asked him one day. She came from Paris, he told me. She may be American, she may be Belgian, or she may be English. She speaks English and French so well that nobody can tell her true nationality.”

“And she makes money at the tables,” said the American woman in the well-cut coat and skirt and small hat. She came from Chelsea, Mass., and it was her first visit to what her pious father had always referred to as the plague spot of Europe.

“Money!” exclaimed the old woman. “Money! Dieu! She has losses, it is true, but oh!—what she wins! I only wish I had ten per cent of it. I should then be rich. Mine is a poor game, madame—waiting for someone to buy my seat instead of standing the whole afternoon. You see, there is only one row of chairs all around. So if a smart woman wants to play, some man always buys her a chair—and that is how I live. Ah! madame, life is a great game here in the Principality.”

Meanwhile young Hugh Henfrey, who had travelled from London to the Riviera and identified the mysterious mademoiselle, had passed with his friend, Walter Brock, through the atrium and out into the afternoon sunshine.

As they turned upon the broad gravelled terrace in front of the great white facade of the Casino amid the palms, the giant geraniums and mimosa, the sapphire Mediterranean stretched before them. Below, beyond the railway line which is the one blemish to the picturesque scene, out upon the point in the sea the constant pop-pop showed that the tir-aux-pigeons was in progress; while up and down the terrace, enjoying the quiet silence of the warm winter sunshine with the blue hills of the Italian coast to the left, strolled a gay, irresponsible crowd—the cosmopolitans of the world: politicians, financiers, merchants, princes, authors, and artists—the crowd which puts off its morals as easily as it discards its fur coats and its silk hats, and which lives only for gaiety and without thought of the morrow.
