The Arab by this time realizes why he is so anxious, and hesitates a little before making reply.

"We must watch and wait. Monsieur will see something soon. Watch the soldier."

This gives John a new idea, and he speedily discovers that Sir Lionel is not idle. The soldier has been in too many desperate situations to be dismayed over such a trifling thing as this.

He is not bound, and hence can move about. Now he seems to be talking to the professor, and anon with Aunt Gwen. Last of all he speaks to Lady Ruth, who nods eagerly.

And a strange feeling comes up in John's mind as he surveys this scene. What causes him to remember the harbor of Malta, the words of the boatman before leaving the steamer, the tragic scene in the blue waters?

It comes over him like a flash. Perhaps he did Sir Lionel an injustice when he suspected him of criminal plotting in such a case, but the circumstances were decidedly against the man.

If he could be guilty of such a scheme, what would he not do in order to win favor at the hands of the young English beauty?

Again it flashes through John's mind; did not the driver in speaking of the facts tell Mustapha that in his opinion it was a man who had entered into a conspiracy with Bab Azoun?

John's first thought was of Pauline Potter—that she had hoped to get hold of him; but now he changes his mind, and locates the trouble elsewhere, fixing it upon the veteran.

Under these circumstances it may be interesting to see how the Briton intends working his plan. John's only desire is a sincere wish that Lady Ruth may be rescued from her predicament. He has no wish to put her to any unnecessary trouble in order that he may play the hero. As well Sir Lionel as any one else, so long as she is benefited.
