'No,' answered the girl, 'it was I who wronged you. I let you go, and said, Go under the ice and be drowned, I did not care.'
'I did not hear you.'
'I said it—instead of telling you of your danger. I was angry—very angry, and I was hurt by Kainie—but'—she hesitated, her voice faltered—'at the bottom of all was this—I was jealous.'
'Jealous? Jealous of whom?'
'Mark, you had been so kind to me. I had been so happy with you. I even thought you liked me. Then you turned away from me for Kainie.'
'For Kainie?'
There was surprise in his face.
'Yes, you like her best. You are right—she is good, and I am bad—but it made me jealous.'
'Good heavens! You do not understand. There is now no need for further concealment. Kainie is my sister!'
