Mildred had no time to whisper more, as the girl ran up to them and caught hold of Roy's two hands with an exclamation of pleasure.
'Dear Roy, this is so good of you, and on my birthday too. Was Aunt Milly in your secret? did she contrive this delightful surprise? I shall scold you both presently, but not now. Come, they are all waiting; how they will enjoy the fun,' and she was actually trying to drag him with gentle force, but the poor lad resisted her efforts.
'I can't—don't ask me, Polly; please let me go. There, I did not mean to hurt your soft, pretty hand, but you must not detain me. Aunt Milly will tell you; at least there is nothing to tell, only I must go away again,' finished Roy, turning away, not daring to look at her, the muscles of his face quivering with uncontrollable emotion.
Polly gave a terrified glance at both; even Aunt Milly looked strangely guilty, she thought.
'Yes, let him go, Polly,' pleaded Mildred.
'What does it all mean, Aunt Milly? is he ill, or has something happened? Why does he not look at me?' cried the girl, in a pained voice.
Roy cast an appealing glance at Mildred to help him; the poor fellow's strength was failing under the unexpected ordeal, but Mildred's urgent whisper, 'Go by all means, leave her to me,' reached Polly's quick ear.
'Why do you tell him to go?' she returned resentfully, interposing herself between them. 'You shall not go, Roy, till you have looked at me and told me what has happened. Why, his hand is cold and shaking, just as yours did that hot night, Aunt Milly,' and Polly held it in both hers in her simple affectionate way. 'Have you been ill, Roy? no one has told us;' but her lips quivered as though she had found him greatly changed.
'Yes—no; I believe I must be ill;' but Mildred, truthful woman, interposed—
'He has not been ill, Polly, but something has occurred to vex him, and he is not quite himself just now. He has told Richard and me, and we think the best thing will be for him to go away a little while until the difficulty lessens.' Mildred was approaching dangerously near the truth, but she knew how hard it would be for Polly's childish mind to grasp it, unless Roy were weak enough to betray himself. His working features, his strange incoherence, had already terrified the girl beyond measure.
