The air was oppressive and she wished herself out in the Pare Monceau, in the May morning. The time seemed endless. By sheer force of habit she slowly turned on the revolving stool and touched the keys; then she struck a few chords softly, and the sound of the perfect instrument gave her pleasure. She played something, trying to make as little noise as possible so long as she remembered where she was, but presently she forgot herself, her lips parted and she was singing, as people do who sing naturally.

She sang the waltz song in the first act of Gounod's Romeo and Juliet, and after the first few bars she had altogether forgotten that she was not at home, with her own piano, or else standing behind her teacher's shoulder in the Boulevard Malesherbes.

Now there are not many singers living who can sing the waltz song and accompany themselves without making a terrible mess of the music; but Margaret did it well, and much more than well, for she was not only a singer with a beautiful voice but a true musician. There was not a quaver or hesitation in her singing from beginning to end, nor a false note in the accompaniment.

When she had finished, her lips closed and she went on playing the music of the scene that follows. She had not gone on a dozen bars, however, when a head appeared suddenly round the corner of a picture on an easel.

'Ah, bah!' exclaimed the head, in an accent of great surprise.

Its thick dark-brown hair was all towzled and standing on end, its brown eyes were opened very wide in astonishment, and it was showing magnificently strong teeth, a little discoloured.

Margaret sprang to her feet with an apology for having forgotten herself, but the head laughed and came forward, bringing with it a large body wrapped in an enormous gown of white Turkish towelling, evidently held together by the invisible hands within. Margaret thought of the statue of Balzac.

"Margaret sprang to her feet with an apology."

'I thought it was Caravita,' said Madame Bonanni. 'We are great friends you know. I sometimes find her waiting for me. But who in the world are you?'
