Since getting into the train the afternoon before the comrade in Elsie had not been visible. The girls had spoken to each other only in monosyllables and with eyes usually averted. Almost as though they had agreed upon it, however, they played up a little in the presence of their aunt. She had been so kind to them and counted so much on the day together to have made them friends, they had not the heart to let her see just how things stood between them. So at dinner they had told her of the day’s adventures vivaciously, dwelling most on their reactions to “The Blue Bird” and the episode of the post. For some reason Elsie did not mention the young man who had shadowed them in such an unshadowy way. That omission surprised Kate and gave her pause. What did such reticence mean? Aunt Katherine had been much diverted by Kate’s account of her interview with the box-office clerk and the manager. Her comment had been, “You are a Frazier, Kate! You have a spine. I imagine the manager sensed that.”

After dinner the three had settled to a quite exciting game of Mah Jong. No need for Elsie and Kate to pretend friendliness then, for the game took all their attention, and they could forget each other as persons. After that there was a brief stroll in the garden, Aunt Katherine walking between the girls, their arms drawn through hers. It had all seemed very peaceful and congenial. But there had been no “good-nights” upstairs, though in accordance with Aunt Katherine’s will the doors stood open between the two bedrooms.

So now, when Aunt Katherine left to attend to the moving of the furniture, Kate turned to Bertha and said, “I shall be in the garden over by the Dentons’ hedge, writing letters. Will you call me when Miss Frazier is ready, Bertha?”

Without a glance at Elsie she picked up her pad and hurried out. She hoped that Elsie realized she was avoiding using the sitting-room and the desk they were supposed to share; and she would not have minded knowing that Elsie’s conscience bothered her about it. But if it did, Elsie gave no sign. She herself simply turned away about some business of her own.

There was so much for Kate to tell her mother in this letter that was interesting and wonderful! First, of course, there was Madame Pearl and her most unique shop that didn’t look like a shop a bit. She must describe the frocks they had chosen, or rather that Madame Pearl had chosen for them; Kate realized now that they themselves had done no choosing at all. Then dining in the luxurious club—she would describe that in detail. She had never in her life had quite such a stimulating conversation with any one before as that conversation at luncheon. She recalled it now as an hour during which she had thought, and thought rapidly, and expressed her thoughts to an attentive listener who in her turn thought and came back at her in a most provocative manner. Ideas had spun in the air between them like iridescent bubbles, changing colour as they turned and you viewed different sides of them. The truth about that was that two most congenial minds had discovered each other, and that is as exciting an adventure as there is in the world, and not at all an ordinary one. The thing that gave this experience its final tang was that the two minds, though comprehending each other perfectly, worked entirely differently. It followed that for each other they had great discoveries and surprises. Together they danced as one in figures new to both!—Of course, Kate could not tell her mother exactly this, but she could tell her enough so that she would understand a little what had happened. But she must begin.

Instead, unhygienically, she sucked the end of her pencil.

Would Mother approve of her having accepted the party frock? That bothered her a little. Knowing Aunt Katherine now she understood her mother much less than ever before on these points. The dress must have cost—no, she would not imagine what it must have cost since Aunt Katherine had told her not to give that end of it a thought. Still, she would describe the dress to Mother, and she could come to conclusions for herself.

“Dearest Mother”:—Oh, there was so much, so very much, it was quite hopeless to write! There was the fairy in the glass. That must be told first. There was not the slightest doubt in Kate’s mind that the two were exactly the same, the fairy in the woods that day and the reflection of Elsie in the mirror at Madame Pearl’s. But what its explanation could be was unthinkable. At the time the little Kate had seen the fairy in the woods, Elsie was only a little girl of her own age. How, then, had Kate seen her as she would look eight years later in a mirror in a Boston shop? It was such an unanswerable question that Kate’s mind turned away from it. Still, not for one minute did she doubt that the two visions had been exactly the same. What would Katherine make of it?

“Hello. Good morning.” Jack Denton, in white flannels, tall and athletic, was standing the other side of the hedge, swinging his tennis racket and smiling a friendly, frank smile. “Excuse me, but you’re Miss Kate Marshall, aren’t you? My sister and I are coming to the party in your honour to-night. I’m Jack Denton, and Rose will be out in a minute. If you’ll play a set with us I’ll call up another fellow and make doubles.”

Kate jumped up, delighted. She went to the wall. “Good morning,” she said. “I was just beginning a letter. But I’d love to play—that is, for a little while, till Aunt Katherine needs me. But why don’t we just shout for Elsie? She likes tennis, I know, and Aunt Katherine says she plays wonderfully.”
