"Because Verschoyle was leaning over the side of the ship when the new passengers were coming up, and he must have recognised him, especially when Mrs. Verschoyle told him she had seen her former husband; he would then be on the look-out for him."

"Humph!--yes--no doubt," replied Foster, thoughtfully. "Can you tell us anything else, Miss Cotoner?"

"Nothing," she answered, rising to her feet, "except that Vassalla told me my sister had committed the crime, and instructed me to deny seeing her on board, which I did--I wrote to you," turning to to Monteith.

"Yes, I understood your letter," he said, gently; and Carmela flashed a grateful look at him.

"Vassalla said he was the only one who could bring the crime home to my sister," she went on, "and made me promise to marry him as the price of his silence."

"But you will not do so?" cried Monteith.

"What can I do?" she said, helplessly. "I cannot see my sister accused of such a crime, when I know it is in my power to prevent it."

"He won't accuse her," broke in Foster, bluntly.

"Then you think she is innocent?" said Carmela, joyfully.

"I don't know that," answered Foster; "the whole affair seems to lie between your sister and Vassalla. He knows more about this affair than we think. Your sister is in England--is she not?"
