He sprang to his feet, and stood before Miss Hamilton, with his eyes fixed angrily upon her face. "If I could tell you everything! Oh, I am outdone with this!" he cried, with a gesture of contempt.

"Captain Paul Jones," she said, rising quickly to confront him, "I beg you to tell me everything. I cannot believe that Roger Wallingford is a traitor, and I love his mother almost as if she were my own. I came to England with her of my own wish and free will, and because it was my right to come. Will you tell me plainly what has happened, and why you do not take his part?"

The captain's quick change from such deep sympathy as he had shown for her tears to a complete scorn of their cause could only give a sad shock to Mary Hamilton's heart. He was no helper, after all. There came a dizzy bewilderment like a veil over her mind; it seemed as if she felt the final blow of Fate. She had not known how far she had spent her strength, or how her very homesickness had weakened her that day.

"I fear it is true enough that he betrayed us at Whitehaven," said Paul Jones slowly, and not unmindful of her piteous look. "I could not bring myself to doubt him at first; indeed, I was all for him. I believe that I trusted him above every man on board. I was his champion until I found he had been meddling with my papers,—my most secret dispatches, too; yes, I have proof of this! And since then some of the stolen pages have found their way into our enemies' hands. He has not only betrayed me, but his country too; and worst of all in men's eyes, he has sinned against the code of honor. Yet there is one thing I will and must remember: 't is never the meanest men who serve their chosen cause as spies. The pity is that where success may be illustrious, the business asks completest sacrifice, and failure is the blackest disgrace. 'Tis Wallingford's reward. I loved him once, and now I could stand at the gallows and see him hanged! Perhaps he would say that he acted from high motives,—'t is ever a spy's excuse; but I trusted him, and he would have ruined me."

"I do not believe that he is guilty," declared Mary Hamilton, with perfect calmness, though she had drawn back in horror as she heard the last words and saw such blazing anger in Paul Jones's eyes. "You must look elsewhere for your enemy," she insisted,—"for some other man whose character would not forbid such acts as these. If Roger Wallingford has broken his oath of allegiance, my faith in character is done; I have known him all my life, and I can answer for him. Believe me, there is some mistake." Her eyes did not fall; as the captain held them straight and answerable with his own she met the challenge of his look, and there came a beautiful glow of pity and gentleness upon her face.

The captain gave a long sigh.

"I am sure that you are mistaken," she said again, quietly, since he did not speak. "We are now in great trouble, and even despair, about Mr. Wallingford, and have been able to get no word from him. We have his pardon in hand; it would make you wonder if I told you how it came to us. Your lieutenant was left most cruelly wounded on the shore at Whitehaven, and was like to die on the long journey to Plymouth jail where they sent him. How he has lived through all his sufferings I do not know. I have seen the Mill Prison, myself; they would not even let us speak with those who knew him among our poor captives. The night before we reached the prison he had escaped; there were some men shot down who were of his party. We can get no trace of him at all. Whether he is dead on the great moors, or still alive and wandering in distress, no one can tell. This does not look as if he were a spy for England; it were easy to give himself up, and to prove such a simple thing, if only to be spared such misery. I am afraid that his mother will soon fade out of life, now that, after all these weeks, she believes him dead. She thought he would return with us, when she saw us ride away to Plymouth, and the disappointment was more than she could bear."

The bitter memory of that morning at the Mill Prison was like a sword in Mary's heart, and she stopped; she had spoken quickly, and was now trembling from head to foot. "I thought, when I saw your face, that you would know how to help us find him," she said sorrowfully, under her breath.

"If I have been wrong," exclaimed the captain, "if I have been wrong, I should give my life to make amends! But all the proofs were there. I even found a bit of one of my own papers among his effects,—'t was in a book he had been reading. But I hid the matter from every one on board; I could not bear they should know it. Dickson's word was their mainstay at first; but that counted worse than nothing to me, till there were other matters which fully upheld his account."

"Dickson has always been a man mistrusted and reproached," protested Miss Hamilton, with indignation. "There is a man for you whose character would not forbid such treachery! You must know, too, that he has a deep hatred for the Wallingfords, and would spare no pains to revenge himself."
