As time went on Nero's confidence in his British guard steadily increased. He had his spies, and knew how entirely Beric kept himself aloof from intimate acquaintanceship with any save the family of Norbanus, and learned, too, that he had refused many large bribes from suitors. For a time, although he knew it not, Beric was constantly watched. His footsteps were followed when he went abroad, his conversations with others in the baths, which formed the great centres of meeting, and stood to the Romans in the place of modern clubs, were listened to and noted. It was observed that he seldom went to convivial gatherings, and that at any place when the conversation turned on public affairs he speedily withdrew; that he avoided all display of wealth, dressed as quietly as it was possible for one in the court circle to do, and bore himself as simply as when he had been training in the ludus of Scopus. There he still went very frequently, practising constantly in arms with his former companions, preferring this to the more formal exercises of the gymnasium. Thus, after a time, Nero became confirmed in his opinion of Beric's straightforward honesty, and felt that there was no fear of his being tampered with by his enemies. One result of this increased confidence was that Beric's hours of leisure became much restricted, for Nero came to require his attendance whenever he appeared in public. With Beric and Boduoc among the group of courtiers that followed him, the emperor felt assured there was no occasion to fear the knife of the assassin; and it was only when he was at the baths, where only his most chosen friends were admitted, or during the long carousals that followed the suppers, that Beric was at liberty, and in the latter case Boduoc was always near at hand in case of need. Nero's precautions were redoubled after the detection of the conspiracy of Piso. That this plot was a real one, and not a mere invention of Nero to justify his designs upon those he hated and feared, is undoubted. The hour for the attempt at assassination had been fixed, the chief actor was prepared and the knife sharpened. But the executions that followed embraced many who had no knowledge whatever of the plot. Seneca was among the victims against whom there was no shadow of proof.
