"But if you won't come, Betty dear, I shan't wish to give the party," Meg Everett announced in a disappointed fashion. "With Polly and Esther not to be here, there are so few of our old Camp Fire circle anyhow. And you see I only wanted to have our club and a few of John's young men friends. The idea is that we girls are to cook the entire dinner and then just talk or dance or play games afterwards. It is not to be anything like a _real_ party." Betty smiled. She and Meg and Mollie O'Neill were taking a winter tramp through the woods in the direction of the Sunrise Cabin, which had been closed for the past six months. "I should dearly love to come, Meg," Betty confessed. "There is no use in my pretending that I shouldn't feel desperately lonely with the thought of your having such a good time without me. But mother----" Mollie gave her arm an affectionate squeeze. "There, Betty Ashton, that is just exactly what I knew you would say. So I talked the whole matter over with your mother myself first. And she declares that there isn't any reason why you should not accept Meg's invitation. She is quite sure that your father would never have wished you not to be as happy as possible. You have had trouble enough, goodness knows! And then the extra disappointment of Polly's and Esther's remaining in New York! I am glad enough Meg is going to give a party, and I hope there will be dozens of delightful things that Polly O'Neill will miss. What on earth do you suppose has possessed her to want to stay on with Esther?" And Mollie sighed. The three months without her sister may have passed by in greater peacefulness than with her, but then Polly always added a zest and flavor to existence. And this was the longest time that the two girls had ever been separated. "Oh, I don't know. She must have had some very good reason," Betty returned. "Polly wrote me that she had, and now we must not believe that she did not love us as much as ever. She wasn't able to explain the particulars just at present; but if we only trust her and forgive her some day we will understand." Mollie frowned. With a much quieter and more amiable temperament than her twin, yet nearly eighteen years of intimate living with her had given her a pretty clear comprehension of her sister's character. Privately Mollie was puzzled over Polly's behavior and a good deal worried. It was not like Polly to have conceived so sudden a devotion to Esther as to be unwilling to leave her for two weeks. And her claim that she might not be particularly happy at home because of her stepbrother's presence was not convincing. For Betty Ashton had invited Polly to be her guest. No, Polly certainly had some special design in staying on in New York. Of this Mollie was completely convinced. But what the purpose was, neither from her own imaginings nor from any hint dropped by her sister's letters, could she get the slightest clue.
