She was silent, thinking. Then she sighed. "I will accept the invitation, Tunis. But I feel--I feel that all is not for the best. But what must be must be. So--oh, I'll go!" CHAPTER XVI MEMORIES--AND TUNIS The benison of that most beautiful season of all the year, the autumn, lay upon Wreckers' Head and the adjacent coast on that Sunday morning. Alongshore there is never any sad phase of the fall. One reason is the lack of deciduous trees. The brushless hills and fields are merely turned to golden brown when the frosts touch them. The sea--ever changing in aspect, yet changeless in tide and restraint--was as bright and sparkling as at midsummer. Along the distant beaches the white ruffle of the surf seemed to have just been laundered. The green of the shallows and the blue of the deeper sea were equally vivid. When she first arose Sheila Macklin looked abroad from that favorite north window of her bedroom, and saw that all the world was good. If she had felt secret misgivings and the tremor of a nervous apprehension, these feelings were sloughed away by this promising morning. The fear she had expressed to Tunis Latham the evening before did not obsess her. She continued placid and outwardly cheerful. Whatever threatened in the immediate future, she determined to meet it with as much composure as she could summon. Nobody but Sheila Macklin knew wholly what she had endured since leaving her childhood's home. When Tunis Latham had come so dramatically into her life she had been almost at the limit of her endurance. To him, even, she had not confessed all her miseries. To escape from them she would have embraced a much more desperate expedient than posing as Ida May Bostwick. The ethics of the situation had not really impressed her at first. The desire to get away from her unfortunate environment, from the city itself, and to go where nobody knew her history, not even her name, was the main thought at that time in the girl's mind. Tunis Latham's confident assurances that she would be accepted without question by Cap'n Ball and Prudence caused her to put aside all fear of consequences at the moment. It was a desperate stroke, but she had been in desperate need, and she had carried the matter through boldly. Now that she seemed so securely established in the Ball household and was accepted by all the community of Big Wreck Cove as the real Ida May, it seemed foolish to give way to anxiety. Discovery of the imposture was remote. Yet, as she had hinted to Tunis, she had an undercurrent of feeling--a more-than-faint apprehension--that all was not right. Something was lurking in the shadows of the future which menaced their peace and security. She was ever mindful of the fact that Tunis had gone sponsor for her identity as Ida May. Should her imposture be revealed, her first duty would be to protect him. How could she do this? What tale could she concoct to make it seem that he was as much duped as were Cap'n Ball and Prudence?
