It was commonly said in the palace that the letter was a forgery concocted by one of the secretaries and sealed with a counterfeit seal. Whilst, however, there was as yet no clear evidence, only suspicion, Xychus happened to meet Antigonus, who had him promptly arrested and conveyed to the palace. Leaving him there under guard he went in to Philip and said to the king: "I think I have understood from my many conversations with you that you would value very highly the opportunity of learning the whole truth about your sons, which of them was the victim of the cunning and treachery of the other. The one man in the whole world who can unravel the knot, namely Xychus, is in your hands. I met him by chance and had him brought to the palace; order him to be summoned." When brought in he at first denied everything, but with such hesitancy that a moderate appeal to his fears would obviously make him a ready informer. The sight of the executioner with his scourge was too much for him, and he explained in full detail the villainy of the two envoys and the way he had acted as their tool. Men were at once despatched to arrest them. Philocles was seized on the spot; Apelles, who had been in pursuit of a certain Chaereas, on learning that Xychus was turned informer, sailed for Italy. The fate of Philocles is not certain. According to some writers he, at first, stoutly denied; afterwards, confronted with Xychus, he no longer held out. Others say that even when put to the torture he still maintained his innocence. Philip's grief and distress were awakened afresh. He considered that the unhappiness caused by his children was made more painful by the survival of the one than by the death of the other.
