Mrs. Raby was a widow of about fifty years of age, of good family and considerable fortune of her own. When a romantic girl of twenty-two she had eloped with a man some twenty years her senior, who happened to be one of the greatest, if not absolutely the greatest, pianists of his day. For a long time her parents and friends held aloof from her. Artists were all very well in their way, but Constance Raby, with her money and good looks—she was an heiress through her godmother—ought to have made a brilliant match.

But Mrs. Raby loved her long-haired musician, the more perhaps for the fact that he was an Englishman, and never repented her choice. And in time, parents and friends condescended to bury the hatchet and came to her house, exchanging frigid courtesies with the artistic husband.

To their drawing-rooms flocked the élite of the musical world—great sopranos, great contraltos, nearly every artist of eminence. And in that charming house in Kensington Gore they gave for nothing what they demanded high fees for elsewhere, for was not the host one of their own world, and had they not adopted his charming wife as one of themselves?

Mr. Raby had died some ten years ago, but his widow still maintained the fame of those musical evenings. And to those who had still their way to make, an appearance in Mrs. Raby’s drawing-rooms conferred a cachet.

Mosenstein had secured an invitation for his young client. There was no fee. When Nello had demurred to this, not quite understanding the situation, the astute agent had silenced his objections at once.

“You do not understand, my young friend. England is a very funny place. A lot is done here for love. Mrs. Raby occupies a unique position. Supposing you were unknown, to play at one of her evenings would secure you a twenty-guinea engagement in South Kensington. Patti, Lucca, Nielson have sung there for friendship. Sarasate has played there for friendship. My friend, if you are wise, you will be glad that I have procured you an invitation.”

Nello made no further objection. Mosenstein knew the ropes as well as anybody. If he urged him to go to the house in Kensington Gore and play for nothing he had a wise motive. Mrs. Raby was evidently a power in the musical world.

The drawing-rooms were crowded, mostly with musical people. But there were a few others from another world; and amongst these, Nello presently discovered his patroness, Lady Glendover, who came here out of sheer love of music. The Countess had to pay five hundred or more for what Mrs. Raby got for nothing.

She greeted Nello kindly and invited him to sit beside her.
