"The whole case is as clear as day," said I. "Felix was in love with Miss Bellin, and wished to marry her. Knowing she was in love with you, he was well aware he had no chance, so resorted to trickery. When you left for Chili, he gave her your letters for three months, then saying he was going abroad, ostensibly left England, but really stayed, and presented himself as--you."

"As me!"

"Yes. He has traded on the marvelous resemblance between you. He knows all your life, all your love affairs, and I have no doubt that Miss Bellin believes that he is Francis Briarfield, her lover, returned from South America in three months instead of six."

"If I thought so," muttered Francis, biting his fingers, "if I thought so----"

"I am sure it is so. Now you see why it is imperative that he should interview you before you meet Miss Bellin. He wishes to reveal the deception and throw himself on your mercy."

"He'll get no mercy from me if this is so," said Briarfield, in a somber tone. "Oh, fool that I was not to write direct to Olivia when I came back to England! But it is not too late. When he comes here I'll learn the truth, and denounce him to Olivia. Then our troubles will be over."

"A man capable of such a trick is capable of worse," said I sententiously. "I advise you to be on your guard against Felix."

"Do you think he'll kill me?"

"I don't go as far as that," I replied cautiously; "but your meeting will be--productive of trouble. Just now you expressed a wish to kill him."

"And I shall, if he has tricked me as you say."
