She was one of those numerous players who bring to the Casino a certain amount daily, and systematically stop playing when they have either lost their money or won a previously determined maximum.

This method, in fact, when combined with a careful system, is the only one whereby even a rich individual can indulge in a costly pastime, and, at the same time, escape speedy ruin. With a fair share of luck it may be made to pay; with continuous bad fortune the loss is spread over such a period that common sense has some opportunity to rescue the victim before it is too late.

Claude took up a position from which he could note the actions of the stranger in whom he was so interested. At first, Mensmore staked nothing. He placed a small pile of gold in front of him; he seemed to listen expectantly to the croupier’s monotonous cry—“Vingt-sept, rouge, impair, passe,” or “Dixhuit, noir, pair, manque,” and so on, while the little ivory ball whirred around the disc, and the long rakes, with unerring skill, drew in or pushed forward the sums lost or won.

The dominant expression of Mensmore’s face as he sat and listened was one of disappointment. Something for which he waited did not happen. At last, with a tightening of his lips and a gathering sternness in his eyes, he placed five louis on the red, the number previously called being thirteen.

Black won.

For the next three attempts, each time with a five louis stake on the board, Mensmore backed the red, but still black won.

Next to him, an Italian, betting in notes of a thousand francs each, had quadrupled his first bet by backing the black.

Both men rose simultaneously, the Italian grinning delightedly at a smart Parisienne, who joyously nodded her congratulations, the Englishman quiet, utterly unmoved, but slightly pallid.

He passed out into the foyer and stopped to light a cigarette. Bruce noticed that his hand was steady, and that all the air of excitement had gone.

These were ill signs. There is no man so calm as he who has deliberately resolved to take his own life. That Mensmore was ruined, that he was hopelessly in love with a woman whom he could not marry, and that he was about to commit suicide, Bruce was as certain as though the facts had been proved by a coroner.
