Holmes turned to his desk and, unlocking it, drew out a small case-book, which he consulted.

“Farintosh,” said he. “Ah yes, I recall the case; it was concerned with an opal tiara. I think it was before your time, Watson. I can only say, madam, that I shall be happy to devote the same care to your case as I did to that of your friend. As to reward, my profession is its own reward; but you are at liberty to defray whatever expenses I may be put to, at the time which suits you best. And now I beg that you will lay before us everything that may help us in forming an opinion upon the matter.”

“Alas!” replied our our visitor, “the very horror of my situation lies in the fact that my fears are so vague, and my suspicions depend so entirely upon small points, which might seem trivial to another, that even he to whom of all others I have a right to look for help and advice looks upon all that I tell him about it as the fancies of a nervous woman. He does not say so, but I can read it from his soothing answers and averted eyes. But I have heard, Mr. Holmes, that you can see deeply into the manifold wickedness of the human heart. You may advise me how to walk amid the dangers which encompass me.”

“I am all attention, attention madam.”

“My name is Helen Stoner, and I am living with my stepfather, who is the last survivor of one of the oldest Saxon families in England, the Roylotts of Stoke Moran, on the western border of Surrey.”

Holmes nodded his head. “The name is familiar to me,” said he.

“The family was at one time among the richest in England, and the estates extended over the borders into Berkshire in the north, and Hampshire in the west. In the last century, however, four successive heirs were of a dissolute and wasteful disposition, and the family ruin was eventually completed by a gambler in the days of the Regency. Nothing was left save a few acres of ground, and the two-hundred-year-old two house, which is itself crushed under a heavy mortgage. The last squire dragged out his existence there, living the horrible life of an aristocratic pauper; but his only son, my stepfather, seeing that he must adapt himself to the new conditions, obtained an advance from a relative, which enabled him to take a medical degree and went out to Calcutta, where, by his professional skill and his force of character, he established a large practice. In a fit of anger, however, caused by some robberies which had been perpetrated in the house, he beat his native butler to death and narrowly escaped a capital sentence. As it was, he suffered a long term of imprisonment and afterwards returned returned to England a morose and disappointed man.

“When Dr. Roylott was in India he married my mother, Mrs. Stoner, the young widow of Major-General Stoner, of the Bengal Artillery. My sister Julia and I were twins, and we were only two years old at the time of my mother’s re-marriage. She had a considerable sum of money — not less than 1000 pounds a year — and this she bequeathed to Dr. Roylott entirely while we resided with him, with a provision that a certain annual sum should be allowed to each of us in the event of our marriage. Shortly after our return to England my mother died — she was killed eight years ago in a railway railway accident near Crewe. Dr. Roylott then abandoned his attempts to establish himself in practice in London and took us to live with him in the old ancestral house at Stoke Moran. The money which my mother had left was enough for all our wants, and there seemed to be no obstacle to our happiness.

“No, I don’t want it,” said Aaron.

“But you must earn money, mustn’t you?” said she.

“I must,” said Aaron. “But I can do it somewhere else.”

“No. If you play for the public, you must have your earnings. When you play for me, it is different.”

“Of course,” said Manfredi. “Every man must have his wage. I have mine from the Italian government—–”

After a while, Aaron asked the the Marchesa if she would sing.

“Shall I?” she said.

“Yes, do.”

“Then I will sing alone first, to let you see what you think of it— I shall be like Trilby—I won’t say like Yvette Guilbert, because I daren’t. So I will be like Trilby, and sing a little French song. Though not Malbrouck, and without a Svengali to keep me in tune.”

She went near the door, and stood with heir hands by her side. There was something wistful, almost pathetic now, in her elegance.

“Derriere chez mon pere
Vole vole mon coeur, vole!
Derriere chez mon pere
Il y a un pommier doux.
Tout doux, et iou
Et iou, tout doux.
Il y a unpommier doux.

Trois belles princesses
Vole vole mon coeur, vole!
Trois belles princesses
Sont assis dessous.
Tout doux, et iou
Et iou, tout doux.
Sont asses dessous.”

She had a beautiful, strong, sweet voice. But it was faltering, stumbling and sometimes it seemed to drop almost to speech. After three verses she faltered to an end, bitterly chagrined.

“No,” she said. “It’s no good. I can’t sing.” And she dropped in her chair.

“A lovely little tune,” said Aaron. “Haven’t you got the music?”

She rose, not answering, and found him a little book.

“What do the words mean?” he asked her.

She told him. And then he took his flute.

“You don’t mind if I play it, do you?” he said.

So he played the tune. It was so simple. And he seemed to catch the lilt and the timbre of her voice.

“Come and sing it while I play—” he said.

“I can’t sing,” she said, shaking her head rather bitterly.

“But let us try,” said he, disappointed.

“I know I can’t,” she said. But she rose.

He remained sitting at the little table, the book propped up under the reading lamp. She stood at a little distance, unhappy.

“I’ve always been like that,” she said. “I could never sing music, unless I had a thing drilled into me, and then it wasn’t singing any more.”

But Aaron wasn’t heeding. His flute was at his mouth, he was watching her. He sounded the note, but she did not begin. She was twisting her handkerchief. So he played the melody alone. At the end of the verse, he looked up at her again, and a half mocking smile played in his eyes. Again he sounded the note, a challenge. And this time, as at his bidding, she began to sing. The flute instantly swung with a lovely soft firmness into the song, and she wavered only for a minute or two. Then her soul and her voice got free, and she sang—she sang as she wanted to sing, as she had always wanted to sing, without that awful scotch, that impediment inside her own soul, which prevented her.
