Nordheim perceived this and smiled, while, without giving his niece a chance to reply, he continued:

"You may rely upon it. But we must first of all try to make you more at home in Europe, where you are positively a stranger. I shall be glad if my house can in any wise contribute to your pleasure; I pray you to believe that you will always be welcome here."

He shook his guest's hand with great cordiality and retired. There was a degree of intention in the way in which he had brought the pair together and then left them to themselves, but Erna did not perceive it. She had been in no wise interested in the presentation of the new-comer,--strangers from beyond the seas were no rarity in her uncle's house,--but her first glance at the guest's unusual type of countenance aroused her attention.

Ernst Waltenberg was no longer young,--he had passed forty, and although not very tall his frame was muscular and well-knit, showing traces, however, of a life of exposure and exertion. His face, tanned dark brown by his sojourn for years in tropical countries, was not handsome, but full of expression and of those lines graven not by years, but by experience of life. His broad brow was crowned by close black curls, and his steel-gray eyes beneath their black brows could evidently flash on occasion. There was something strangely foreign about him that set him quite apart from the brilliant but mostly uninteresting personages that crowded Nordheim's rooms. His voice too had a peculiar intonation,--it was deep, but sounded slightly foreign, possibly from years of speaking other tongues than his own. Evidently he was perfectly versed in the forms of society; the manner in which he took his seat beside Fräulein von Thurgau was entirely that of a man of the world.

"You have but lately come from Persia?" Erna asked, referring to what her uncle had said.

"Yes, I was there last; for ten years I have not seen Europe before."

"And yet you are a German? Probably your profession kept you away thus long?"

"My profession?" Waltenberg repeated, with a fleeting smile. "No; I merely yielded to my inclination. I am not of those steadfast natures which become rooted in house and home. I was always longing to be out in the world, and I gratified my desire absolutely in this respect."

"And in all these ten years have you never been homesick?"

"To tell the truth, no! One gradually becomes weaned from one's home, and at last feels like a stranger there. I am here now only to arrange various business affairs and personal matters, and do not propose to stay long. I have no family to keep me here; I am quite alone."
