"But, yes," said Brother Charles, "have they not just installed the Marconi system in the Eiffel Tower? Of course, we know, but not, I think, more than any ordinary member of the public."

"Very well," said Deschamps. "Now I must tell you that Monsieur Gregory here and myself have for years been at work upon a system of transmitting messages without wires, which, we believe, and indeed are certain, surpasses the invention of Signor Marconi as a modern battleship surpasses an ancient wooden frigate. It is this system of ours that I propose to employ in the secret war against the Administration at Monte Carlo. By its means we shall be able to win an enormous sum of money at roulette. We shall be able to win exactly how much, and when, we please. Every detail is perfectly clear in my mind, and discovery is almost impossible with the precautions I shall take. You must remember that the capital of Monte Carlo is unlimited. You know nothing of the place, Basil?"

Gregory shook his head.

"Then, pardon a short digression," Deschamps continued, looking at the Carnets. "The gambling rooms of Monte Carlo pay the Prince of Monaco a yearly subsidy of eighty thousand pounds for permission to carry on their business in his territory. There are no rates and taxes in Monte Carlo, the Casino pays them all. Education is free. The Casino itself is a glittering white palace upon the edge of the Mediterranean, erected at an enormous cost, and decorated with the most lavish splendour. Few kings have such vast halls and salons in their palaces as those in the temple of the Goddess of Chance. The Casino is free to all the world, though, of course, the Administration reserves the right of declining admission. The gardens that surround this palace are the most beautiful in the world. Sometimes, as if by touch of an enchanter's wand, the thousand gardeners steal out in the night, and in the morning vast parterres of flowers, which had been all red and gold as the sun sank, are changed to blue and white. In addition to this—and the expenses of the Principality are incalculable—the company pays a revenue to its shareholders of over twenty-five million francs!"

Basil had been listening with absorbed interest. He started now. "Twenty-five million francs!" he said, in an awed voice. "Clear profit after those colossal expenses? A million English pounds!"

"Exactly," Deschamps returned, "and I have told you this so that you can see that the resources of the company are practically unlimited. The amount of their funds no one knows, but many a national bank could not equal it. So you see, the authorities are pledged for the sake of their own continuance to pay any player his winnings, however enormous they may be. There have been several cases of players quite recently winning sums of two and a half million francs—a hundred thousand pounds of your English money. But we"—here his voice for the first time began to tremble with excitement—"we can win whatever we please! And now to the way in which it is to be done."

Deschamps stopped short in his walk up and down. He leant against the work-table upon which were the remains of the supper.

The eyes of the other three were fixed upon him with an intense regard.

"You understand," he said to Basil, "the principle of roulette, do you not?"

"Roughly," Basil answered; "the little ivory ball about the size of a large marble is spun as you spun it the other night, and falls into a numbered slot. The people who have placed their money upon a square of the table with a number corresponding to that of the slot into which the ball falls are the winners of varying amounts."
