"This is Erich von Harben, a guest in the home of Septimus Favonius, my father," replied the girl, haughtily; and to von Harben, "This is Fulvus Fupus, who accepts the hospitality of Septimus Favonius so often that he feels free to criticize another guest." Fupus flushed. "I apologize," he said, "but one may never know when to honor or when to ridicule one of Septimus Favonius's guests of honor. The last, if I recall correctly, was an ape, and before that there was a black barbarian from some outer village--but they are always interesting and I am sure that the barbarian, Erich von Harben, will prove no exception to the rule." The man's tone was sarcastic and obnoxious to a degree, and it was with difficulty that von Harben restrained his mounting temper. Fortunately, at this moment, Mallius Lepus joined them and von Harben was formally presented to Favonia. Fulvus Fupus thereafter paid little attention to von Harben, but devoted his time assiduously to Favonia. Von Harben knew from their conversation that they were upon friendly and intimate terms and he guessed that Fupus was in love with Favonia, though he could not tell from the girl's attitude whether or not she returned his affection. There was something else that von Harben was sure of--that he too was in love with Favonia. Upon several occasions in life he had thought that he was in love, but his sensations and reactions upon those other occasions had not been the same in either kind or degree as those which he now experienced. He found himself hating Fulvus Fupus, whom he had known scarce a quarter of an hour and whose greatest offense, aside from looking lovingly at Favonia, had been a certain arrogant sarcasm of speech and manner--certainly no sufficient warrant for a sane man to wish to do murder, and yet Erich von Harben fingered the butt of his Luger, which he had insisted upon wearing in addition to the slim dagger with which Mallius Lepus had armed him. Later, when Septimus Favonius joined them, he suggested that they all go to the baths and Mallius Lepus whispered to von Harben that his uncle was already itching to exhibit his new find. "He will take us to the Baths of Caesar," said Lepus, "which are patronized by the richest patricians only, so have a few good stories ready, but save your best ones, like that you told me about the modern Roman litters, for the dinner that my uncle is sure to give tonight--for he will have the best of Castrum Mare there, possibly even the Emperor himself." The Baths of Caesar were housed in an imposing building, of which that portion facing on the avenue was given over to what appeared to be exclusive shops. The main entrance led to a large court where the warmth with which the party was greeted by a number of patrons of the Baths already congregated there attested to the popularity of Favonius, his daughter, and his nephew, while it was evident to von Harben that there was less enthusiasm manifested for Fulvus Fupus.
