As the game went on and the croupier monotonously raked in the winnings of the bank, Paul suddenly divined the motive which had induced the lady to come there. Undoubtedly it was the hope that she might win enough to satisfy the cruel demands of those who persecuted her.

Quite evidently disturbed by his entrance, for the next few minutes she had apparently lost all track of the successful theory which she had been following. And Paul knew well enough that if a good player once becomes unnerved, his luck, for some strange reason, will change with his mood, and no efforts, however bold or desperate, will avail him anything.

It amazed Verdayne beyond measure that the lady could play such a game with so consummate a skill and so much evidence of experience. He judged that at some time or other she had had a little fling at Monte Carlo, and that profiting by such knowledge as she had acquired before, she had now been playing an inspired game for some incalculable stake.

If she won against the bank it would release her from her torment; no other theory was possible.

It made his heart grow cold with rage as he appreciated that he had been made the innocent instrument of such a hard experience for her.

So convinced did he become of this fact that he shouldered his way through the crowd, and leaning over her chair, whispered into her ear:

"Don't be alarmed. I see you have been greatly upset. Please allow me to assist you."

The man at her right hand scowled angrily, but Paul turned to him with an urbane smile. "As you do not seem to be playing," he said, "perhaps you will allow me to have your chair?"

Nor had the man any alternative but to vacate his seat.

Paul's spirits rose as for the first time in his life he found himself seated by the lady's side, playing on her behalf, to win a desperate game.
