“This is the way out,” she announced in an excited whisper; “I feel the door. Oh, I hope it isn’t locked. No, it’s all right; here’s the handle. Oh!” And, with a great gasp, Dulcie stepped out into the lighted hall of the boarding-house.

“That’s her room,” whispered Molly, pointing to one of the closed doors. “Shall I knock, or will you, Dulcie?”

“You’d better,” said Dulcie. “You know her, and we don’t. Be sure not to forget to introduce us.”

Molly stepped forward, and for the second time, tapped softly at the “singing lady’s” door. There was a moment’s pause, and then the sweet voice they had all so often heard singing the old-fashioned ballads they loved, called a cheerful “Come in,” and Molly turned the handle.

Miss Polly was in her wheel-chair, which had been pushed under the rather high chandelier in the centre of the room. She had evidently been reading, but at the children’s entrance she laid down her book, and with a little cry of pleasure, held out both hands in greeting.

“Why, it’s my little neighbors from next door,” she said joyfully. “Oh, but I am glad to see you, dears. And did you all come through the door in the wall?”

“Yes, we did,” said Molly; and, mindful of Dulcie’s instruction, she added, primly, “These are my three sisters; Dulcie, Daisy, and Maud. We came to thank you for being so kind about singing while Maud was in bed, with her sore throat.”

“You are all most welcome, I am sure,” said Miss Polly, heartily, her pretty face fairly beaming with pleasure. “It’s never any trouble to me to sing. I love music more than almost anything else in the world. I would like to be at my piano all day if it were not for fear of troubling the other boarders.”

“I’m sure it couldn’t trouble anybody,” said Dulcie, politely. “We love it.”

“You are very kind to say so, dear, but you see people don’t all feel the same way about things. There was an old gentleman on this floor last year who objected very much. He said music made him nervous, and threatened to leave if he ever heard the piano when he was in his room. Miss Collins was very sorry, but of course she couldn’t run the risk of losing a boarder, so I had to be very careful. Fortunately, he has gone away now, and the young man who occupies the room this winter is scarcely ever at home. Now, won’t you all sit down and make me a nice little visit? I expected to be alone all the evening, for Miss Collins told me she was going to the theatre, and she is about my only visitor. I am sorry I haven’t more chairs to offer you. You see, I have so few visitors, it seemed foolish to waste chairs, so I let Miss Collins take some that belonged in this room and use them somewhere else. Perhaps two of you won’t object to sitting on the bed.”
