There was a new ring in Margaret's voice, a look of resolution on her face that was strange to it, and Eleanor, glancing at her in amazement, realised that she was showing a latent strength of purpose that had perhaps for the first time in her sheltered, uneventful life been called out in her. Nevertheless she refused to believe that Margaret really meant what she said. "But the dishonesty you spoke of just now," she said. "What about that; and your dislike to the deception we are both practising? That remains the same." "I know," said Margaret in a low tone, a shadow crossing her face and dimming the look of courageous resolve it wore. "But that is unavoidable. It seems to me now that it would be quite as bad, if not worse, to break faith with you." Still Eleanor did not give way. Her conscience did not need to speak very loudly for her to hear it telling her that in accepting Margaret's offer she was doing a very wrong thing. In her heart of hearts she had known all along that their plot was inexcusable from every point of view, and that when it came to be known most of the blame would be laid at her door, not only because she was the elder and the more worldly wise of the two, but because most people would consider that she had been the one to profit most by the exchange. But she had been carried away by Margaret's urgent pleadings and persuasions and had finally suppressed her misgivings and consented to the plot. Now, however, the case was altered. It was only out of a spirit of pure self-sacrifice that Margaret was urging her to continue to bear her name, and she knew that in yielding she would be guilty of great selfishness. "Think of your singing lessons with Madame Martelli," said Margaret, who was quietly watching the struggle with herself to which Eleanor's changing face bore eloquent witness. That clenched the matter. Eleanor gave in; but this time it was she who found it difficult to meet Margaret's eyes. "Oh, Margaret," she said, "if you appeal to my ambition my better self goes under. I accept, then; but you're a brick, a perfect brick, and I feel too mean for words." CHAPTER XI A PRACTICAL JOKE
