Ned leaped into the saddle, and with sincere thanks to the man galloped off towards Antwerp. Unless ill fortune should again throw him in the way of Von Aert he now felt safe; and he had no fear that this would be the case, for they would be devoting their whole energy to the search for him in Brussels. He burst into a fit of hearty laughter as he rode along, at the thought of the fury the councillor must have been thrown into when, upon his return home, he discovered that he had given away the wrong packet of letters. He would have been angry enough before at the escape of the captive he was himself watching, and the loss thereby of the means upon which he had reckoned to discover the ownership of the letters, and so to swell the list of victims. Still he doubtless consoled himself at the thought that he was sure before many hours to have his prisoner again in his power, and that, after all, annoying as it was, the delay would be a short one indeed. But when he took the packet from his pocket, and discovered that he had given up the all important documents, and had retained a packet of blank paper, he must have seen at once that he was foiled. He might recapture the prisoner, torture him, and put him to death; but his first step would of course have been to destroy the precious letters, and there would be no evidence forthcoming against those for whom they were intended, and who were doubtless men of considerable standing and position, and not to be assailed upon the mere avowal extracted by torture from a boy and unsupported by any written proofs. "That evil looking clerk of his will come in for a share of his displeasure," Ned thought to himself. "I believe that he is worse than his master, and will take it sorely to heart at having been tricked by a boy. I should have scant mercy to expect should I ever fall into their hands again." Ned rode through the city of Mechlin without drawing rein. It was but a month since that it had been the scene of the most horrible butchery, simply because it had opened its gates to the Prince of Orange on his forward march to attempt the relief of Mons. A few of the prince's German mercenaries had been left there as a garrison. These fired a few shots when the Spanish army approached, and then fled in the night, leaving the town to the vengeance of the Spaniards. In the morning a procession of priests and citizens went out to beg for pardon, but the Spaniards rushed into the town and began a sack and a slaughter that continued for three days.
