Surely no pair, even in the bygone days of knight and dame, the days of real romance, were more devoted to each other. With satisfaction he saw that Gabrielle's apparent indifference had now worn off. It had been but the mask of a woman's whim, and as such he treated it.

One afternoon, after tea out on the lawn, they were walking together by the bypath to the lodge in order to meet Lady Heyburn, who had gone into the village to visit a bedridden old lady. Hand-in-hand they were strolling, for on the morrow he was going south, and would probably be absent for some months.

The girl had allowed herself to remain in her lover's arms in one long kiss of perfect ecstasy. Then, with a sigh of regret, she had held his hand and gone forward again without a word. When Walter had left, the sun of her young life would have set, for after all it was not exactly exciting to be the eyes and ears of a man who was blind. And there was always at her side that man whom she hated, and who, she knew, was her bitterest foe--James Flockart.

Of late her father seemed to have taken him strangely into his confidence. Why, she could not tell. A sudden change of front on the Baronet's part was unusual; but as she watched with sinking heart she could not conceal from herself the fact that Flockart now exercised considerable influence over her father--an influence which in some matters had already proved to be greater than her own.

It was of this man Walter spoke. "I have a regret, dearest--nay, more than a regret, a fear--in leaving you here alone," he exclaimed in a low, distinct voice, gazing into the blue, fathomless depths of those eyes so very dear to him.

"A fear! Why?" she asked in some surprise, returning his look.

"Because of that man--your mother's friend," he said. "Recently I have heard some curious tales concerning him. I really wonder why Sir Henry still retains him as his guest."

"Why need we speak of him?" she exclaimed quickly, for the subject was distasteful.

"Because I wish you to be forewarned," he said in a serious voice. "That man is no fitting companion for you. His past is too well known to a certain circle."

"His past!" she echoed. "What have you discovered concerning him?"

Her companion did not answer for a few moments. How could he tell her all that he had heard? His desire was to warn her, yet he could not relate to her the allegations made by certain persons against Flockart.

"Gabrielle," he said, "all that I have heard tends to show that his friendship for you and for your father is false; therefore avoid him--beware of him."

"I--I know," she faltered, lowering her eyes. "I've felt that was the case all along, yet I----"

"Yet what?" he asked.

"I mean I want you to promise me one thing, Walter," she said quickly.

"You love me, do you not?"

"Love you, my own darling! How can you ask such a question? You surely know that I do!"

"Then, if you really love me, you will make me a promise."

"Of what?"

"Only one thing--one little thing," she said in a low, earnest voice, looking straight into his eyes. "If--if that man ever makes an allegation against me, you won't believe him?"

"An allegation! Why, darling, what allegation could such a man ever make against you?"

"He is my enemy," she remarked simply.

"I know that. But what charge could he bring against you? Why, if even he dared to utter a single word against you, I--I'd wring the ruffian's neck!"

"But if he did, Walter, you wouldn't believe him, would you?"

"Of course I wouldn't."

"Not--not if the charge he made against me was a terrible one--a--a disgraceful one?" she asked in a strained voice after a brief and painful pause.

"Why, dearest!" he cried, "what is the matter? You are really not yourself to-day. You seem to be filled with a graver apprehension even than I am. What does it mean? Tell me."

"It means, Walter, that that man is Lady Heyburn's friend; hence he is my enemy."

"And what need you fear when you have me as your friend?"

"I do not fear if you will still remain my friend--always--in face of any allegation he makes."

"I love you, darling. Surely that's sufficient guarantee of my friendship?"

"Yes," she responded, raising her white, troubled face to his while he bent and kissed her again on the lips. "I know that I am yours, my own well-beloved; and, as yours, I will not fear."

"That's right!" he exclaimed, endeavouring to smile. "Cheer up. I don't like to see you on this last day down-hearted and apprehensive like this."

"I am not so without cause."

"Then, what is the cause?" he demanded. "Surely you can repose confidence in me?"

Again she was silent. Above them the wind stirred the leaves, and through the high bracken a rabbit scuttled at their feet. They were alone, and she stood again locked in her lover's fond embrace.

"You have told me yourself that man Flockart is my enemy," she said in a low voice.

"But what action of his can you fear? Surely you should be forearmed against any evil he may be plotting. Tell me the truth, and I will go myself to your father and denounce the fellow before his face!"

"Ah, no!" she cried, full of quick apprehension. "Never think of doing that, Walter!"

"Why? Am I not your friend?"

"Such a course would only bring his wrath down upon my head. He would retaliate quickly, and I alone would suffer."

"But, my dear Gabrielle," he exclaimed, "you really speak in enigmas.

Whatever can you fear from a man who is known to be a blackguard--whom I could now, at this very moment, expose in such a manner that he would never dare to set foot in Perthshire again?"

"Such a course would be most injudicious, I a.s.sure you. His ruin would mean--it would mean--my--own!"

"I don't follow you."

"Ah, because you do not know my secret--you----"

"Your secret!" the young man gasped, staring at her, yet still holding her trembling form in his strong arms. "Why, what do you mean? What secret?"

"I--I cannot tell you!" she exclaimed in a hard, mechanical voice, looking straight before her.

"But you must," he protested.

"I--I asked you, Walter, to make me a promise," she said, her voice broken by emotion--"a promise that, for the sake of the love you bear for me, you will not believe that man, that you will disregard any allegation against me."

"And I promise, on one condition, darling--that you tell me in confidence what I, as your future husband, have a just right to know--the nature of this secret of yours."
