"But I believed in you then, and replied that you had been engaged by Mr. Warwick to clear up a mystery which surrounded my uncle. However, he said he knew your methods. You had no doubt in some insidious way caused yourself to be suggested to Mr. Warwick for the——"

"Stella!" cried Warwick, in astonishment.

"Is it so surprising that this should be true?" she asked turning to him. "Have not much more surprising things happened of late?"

Warwick made no reply to this, but directed a look toward the secret agent.

"One would have thought," said the latter, composedly, "that Okiu's being so manifestly an interested person would have weakened the plausibility of his story. But," and he smiled as he went on, "perhaps he did not divulge the real nature of the paper." He caught the look that came into her face, and added: "I see that he did not. A clever man would not, and Okiu is really very clever."

He paused for a few moments as though expecting either one or the other to speak; but as they did not do so, remaining cold faced and unbelieving, he resumed:

"I see that there is very little that I can say that will tend toward reëstablishing our first friendly relationship. And this being the case, we shall waste no more time upon the attempt."

There was another brief pause; then he went on: "However, in tracing out this matter, I have come upon indications and have arrived at conclusions which may surprise you still more." His turning of the pages of the note-book stopped, and with his finger marking a penciled entry, he said to Warwick: "This woman in New York—have you settled your matters with her?"
