“He came with magnificent credentials, and an account was opened for him at Coutts’s before he arrived,” said Magnus Dudley, the society poet, flinging back his long hair with a lazy movement of the large languid head. “Of course, you know that he is a natural son of Cavour’s?”

“Indeed! No, I never heard that. He is not like Cavour.”

“Of course not, but he is the image of his mother—one of the handsomest women in Italy—a Duchess, and daughter of a Roman Prince, who could trace his descent in an unbroken line from Germanicus. Castellani has the blood of Caligula in his veins.”

“He looks like it; but I have heard on pretty good authority that he is the son of a Milanese music-master.”

“There are people who will tell you his father wheeled a barrow and sold penny ices in Whitechapel,” retorted Magnus. “People will say anything.”

Thus and in much otherwise did society speculate; and in the meantime Mr. Castellani’s circle was always widening. His book had been just audacious enough and just clever enough to hit the gold in the literary target. Nepenthe had been one of the successes of the season before last: and Mr. Castellani was henceforth to be known as the author of Nepenthe. He had touched upon many things below the stars, and some things beyond them. He had written of other worlds with the confidence of a man who had been there. He had written of women with the air of a Café de Paris Solomon; and he had written of men as if he had never met one.

A man who could write a successful book, and could sing and play divinely, was a person to be cultivated in feminine society. Very few men cared to be intimate with Mr. Castellani, but among women his influence was indisputable. He treated them with a courtly deference which charmed them, and he made them his slaves. No Oriental despot ever ruled more completely than César Castellani did in half-a-dozen of those drawing-rooms which give the tone to scores of other drawing rooms between Mayfair and Earl’s Court. He contrived to be in request from the dawn to the close of the London season. He had made a favour of going to Riverdale; and now, although it suited his purpose to be there, he made a favour of staying.

“If it were not for the delight of being here, I should be in one of the remotest valleys in the Tyrol,” he told Mrs. Hillersdon. “I have never stayed in England so long after the end of the season. A wild longing to break loose from the bonds of Philistinism generally seizes me at this time of the year. I want to go away, and away, and ever away from my fellow-men. I should like to go and live in a tomb, like the girl in Ouida’s In Maremma. My thirst for solitude is a disease.”

This from a man who spent the greater part of his existence dawdling in drawing-rooms and boudoirs sounded paradoxical; but paradoxes are accepted graciously from a man who has written the book of the season. Louise Hillersdon treated Castellani like a favourite son. At his bidding she brought out the old guitar which had slumbered in its case for nearly a decade, and sang the old Spanish songs, and struck the strings with the old dashing sweep of a delicate hand, and graceful curve of a rounded arm.

“When you sing I could believe you as young as Helen when Paris stole her,” said Castellani, lolling along the sofa beside the low chair in which she was sitting; “I cease to envy the men who knew you when you were a girl.”
