He could not account for the change which had come over her. From the time he arrived from Taloona she had always shown kindliness and gentleness towards him, even when, during the early days of his convalescence, he had been impatient and exacting. Nor could he find a reason for the change in the brief profession he had made of his love for her. Had that been the cause she would, he argued, have shown it the morning after; but she had met him then with the same light-hearted raillery with which she had greeted him every morning he had been in her house. Only when Brennan arrived on the scene had she suddenly developed antagonism.

There must be some other reason for her anger than his declaration of love. For hours he had sought for it, cudgelling his brain to discover an explanation; but only now, as he cantered along through the bush with his spirits rising in harmony with the glories of an Australian dawn, did illumination come to him.

"Oh, my love, why have you come so late to me!"

Through the sombre shade of his brooding there flashed the memory of the scene when he had heard those words spoken. Like the touch of a magic wand the memory changed gloom to sunshine, shadow into light.

It was not because he had professed his love for her that she had been displeased; it was because he was going from her, leaving her house, parting with her perhaps for all time.

What a fool he had been not to know that earlier. Of course, she had repelled him when he had spoken on the previous evening, repelled him, not because she resented, but because she, like all of her sex, could not yield the truth at the first asking.

Yet why should he have doubted with the memory of that earlier scene in his mind? He asked himself the question and answered it frankly.

He doubted for the reason that still he did not know whether that memory was of a real scene, or was merely a figment of a delirium-haunted brain. If he could be sure, then no more need he doubt; but how was he to be sure? There was only one way—only one person in all the world who could tell him whether he was right or not—Nora Burke alone could say whether he had been dreaming.

Some day he would ask her to tell him, some day, after he had asked and compelled her to answer that other question which had now become insistent. For the time the mystery of the Rider occupied a second place in his thoughts; yet the trend of his mind unconsciously brought it again to the front.

The mission on which he had set out was one which might clear away the initial obstacle in the pathway of his love; he might locate the hiding-place of the Rider; might secure a clue to his identity; might, by great good fortune, discover the stolen money.
