Arethusa left her chair, and crept nearer and nearer to the musician until she was almost on top of the piano bench herself, in her absorbed interest. Her hands clasped over her heart to still the curious little ache the music made her to feel there, with her lips parted slightly and her eyes like big stars; she had scarcely dared breathe. She wished suddenly for Timothy, for Timothy worshipped music. He loved even to hear her, Arethusa, play. And she was sure he had never heard any music such as this.
It was not what Miss Letitia would have called playing "with expression"; it was not as she had tried to teach Arethusa. Elinor's long, white hands just seemed to wander over the keys, as softly aimless as if she had no slightest idea what the next note was to be; they strayed from themes which aroused to an ecstasy into simple melodies that left a haunting sense that they had not been finished. Sometimes the piano scarcely seemed to sound; sometimes it crashed in grand chords, as if the musician's playing had changed with her mood.
And Arethusa had listened, full of vague longings she did not understand, feeling when it ended that it was ended far too soon; and Ross had smoked silently, blowing great, blue wreaths about his head, one after another. There had been no single word from either to break the spell of the music.
Arethusa wrote away, the wrinkles of composition between her brows and her writing becoming more and more ragged as the letter proceeded. Her feet were twined in the rounds of her chair, her arms were spread out all over the top of the big desk with a great display of elbows, and she was ungracefully humped as to back; for when Arethusa wrote, her whole body responded to the effort.
Close beside her lay Boris, Ross's Great Dane, a dignified animal of unusual beauty. Ordinarily, he was so indifferent and sometimes so disagreeable to strangers that he was rarely allowed where they were, yet he had adopted Arethusa at sight when first introduced just after breakfast, and he had not left her side since. Most people were frightened nearly speechless when Boris merely opened his mouth to yawn; but he had not frightened Arethusa. She had voted him the most wonderful dog she had ever seen, and pleased Ross immensely by her lack of fear.
Every now and then when she stopped in her writing to open her cramped fingers for a moment and gaze admiringly around the room, she would stoop and pat Boris. And she would stroke him wherever her hand happened to fall, and he did not seem to resent it in the least, which was something most unusual.
Ross was in the library, sprawled on the big davenport, and watching the girl and the dog with keen delight in the picture they made. He had never known Boris to make friends thus suddenly, in all the six years he had owned him; even Elinor was a bit afraid of the splendid creature.
Elinor had been in the library also most of the morning, talking to Ross while Arethusa performed a Duty; but she had been called out to the telephone. When she came back, her first words were for Arethusa.
"I have an invitation for you."
"For me!" Arethusa's pen dropped abruptly in the middle of her page to make a large and sprawling splash of ink.
