Theriere was often with her now, and, less frequently, Divine; for at the second officer’s suggestion Barbara had not acquainted that gentleman with the fact that she was aware of his duplicity.

“It is just as well not to let him know,” said Theriere.  “It gives you an advantage that would be wanting should he suspect the truth, so that now you are always in a position to be warned in plenty of time against any ulterior suggestion he may make.  Keep me posted as to all he tells you of his plans, and in this way we can defeat him much more easily than as though you followed your natural inclinations and refused to hold communication of any sort with him.  It might be well, Miss Harding, even to encourage him in the hope that you will wed him voluntarily.  I think that that would throw him entirely off his guard, and pave the way for your early release.”

“Oh, I doubt if I could do that, Mr. Theriere,” exclaimed the girl.  “You cannot imagine how I loathe the man now that I know him in his true colors.  For years he has importuned me to marry him, and though I never cared for him in that way at all, and never could, I felt that he was a very good friend and that his constancy demanded some return on my part—­my friendship and sympathy at least; but now I shiver whenever he is near me, just as I would were I to find a snake coiled close beside me.  I cannot abide treachery.”

“Nor I, Miss Harding,” agreed Theriere glibly.  “The man deserves nothing but your contempt, though for policy’s sake I hope that you will find it possible to lead him on until his very treachery proves the means of your salvation, for believe me, if he has been false to you how much more quickly will he be false to Simms and Ward!  He would ditch them in a minute if the opportunity presented itself for him to win you without their aid.  I had thought it might be feasible to lead him into attempting to take the ship by force, and return you to San Francisco, or, better still possibly, to the nearest civilized port.

“You might, with propriety suggest this to him, telling him that you believe that I would stand ready to assist in the undertaking.  I can promise you the support of several of the men—­quite a sufficient number with Divine and myself, easily to take the Halfmoon away from her present officers.”

“I will think over your suggestion, Mr. Theriere,” replied Barbara, “and I thank you for the generous impulse that has prompted you to befriend me—­heaven knows how badly I need a friend now among so many enemies.  What is it, Mr. Theriere?  What is the matter?”

The officer had turned his eyes casually toward the southeast as the girl spoke, and just now he had given a sudden exclamation of surprise and alarm.

“That cloud, Miss Harding,” he answered.  “We’re in for a bad blow, and it’ll be on us in a minute,” and with that he started forward on a run, calling back over his shoulder, “you’d better go below at once.”
