"It is a poison," she said unsteadily. "A deadly, a horrible poison which drives men murder mad in two weeks from the time of its administration. The Senhor Ribiera has an antidote for it. But mixed with the antidote, which acts at once, is more of the horrible poison, which will act in two weeks more. So that we are entrapped. If we disobey him...."

Bell began to smile slowly, and not at all mirthfully.

"I think," he said softly, "that I shall gain a great deal of pleasure from killing the Senhor Ribiera."

"Dios—" She strangled upon the word. "Do you not see, Senhor, that if he dies we—we—" She stopped and choked. "We—have a tiny baby, Senhor. We—we would...."

Again sick rage surged up in Bell. To kill Ribiera meant to drive his slaves mad, and mad in the most horrible fashion that can be imagined. To kill Ribiera meant to have these people duplicate the death of Ortiz, as their greatest hope, or to fill madhouses with snarling animals lusting to kill....

"It is—it is not only I, Senhor," said the girl before him. She was utterly listless, and in the agony of despair. "It is Arturo, also. The Senhor Ribiera has said that if I do not persuade you, that both Arturo and I.... And our little baby, Senhor!... Our families also will be entrapped some day. He has said so.... He will give that poison to our baby.... And it will grow up either his slave, or—"

Her eyes were pools of panic.

"Oh, God!" said Bell very quietly. "And he's offering me this power! He's trying to persuade me to become like him. He's offering me pleasures!"
