Byrne, looking from one to the other, rubbed his hands and chuckled. "I thought that part of the business would prove a stumbling-block," he said. "But if you will allow me, I can lift you over it very easily. You will have observed that Jacoby's letter enters into no particulars. It gives neither the name of the ship, the date of sailing, nor the port he sailed from. We cannot advance a step beyond the letter till we make ourselves masters of that information. It is quite evident that there is only one source from which we can obtain it, and that is from Jacoby himself. How are we to get out of him any information respecting this, the great secret of his life? Were you or I to question him, we should merely arouse his suspicions and shut his lips for ever. Gentlemen, no one can worm the secret out of this man but a woman--and only a woman that he loves. Gentlemen, Max Jacoby loves my daughter, and has asked her to become his wife. On my daughter, therefore, devolves the duty of making this man reveal what he has probably never told yet to any living soul. And now you understand the point at which we have arrived." "Clearly," said Gerald; "and upon my word, I am doubtful whether the same result could have been arrived at by means other than those which you have seen fit to make use of." Ambrose Murray did not speak, but he put out his arm, and grasped Byrne by the hand in a fashion far more eloquent than words. "If Mr. Byrne will allow me, I will proceed just one step further in the matter," said Gerald. "Assuming for a moment that we have succeeded in getting out of Jacoby all the information we want from him; that we know when and from where he sailed, and the name of the ship--what then? The only evidence on which it would be possible to convict him will still be at the bottom of the sea." Before Byrne could say a word in reply, there came a sudden knocking at the door, and the voice of Bakewell was heard outside: "A letter for Mr. Byrne." Murray, his mind impressed with what had gone before, said solemnly: "Yes, it will still be, what it must remain for ever--a Secret of the Sea!" Byrne held up a warning finger. In one minute he seemed to become twenty years older. He hobbled feebly towards the door, coughing meanwhile in a way that was pitiful to hear. "All right, Bakewell, I'm coming--I'm coming," he cried, querulously. Then, as he opened the door, Miriam's voice was heard carolling gaily as she ran quickly upstairs. CHAPTER VII. POD'S REVELATION.
