Sir Robert Clifford and William Barley were still more open in their measures: they went over to Flanders, were introduced by the duchess of Burgundy to the acquaintance of Perkin, and made him a tender of their services. Clifford wrote back to England, that he knew perfectly the person of Richard, duke of York, that this young man was undoubtedly that prince himself, and that no circumstance of his story was exposed to the least difficulty. Such positive intelligence, conveyed by a person of rank and character, was sufficient with many to put the matter beyond question, and excited the attention and wonder even of the most indifferent. The whole nation was held in suspense; a regular conspiracy was formed against the king’s authority, and a correspondence settled between the malecontents in Flanders and those in England. The king was informed of all these particulars; but agreeably to his character, which was both cautious and resolute, he proceeded deliberately, though steadily, in counterworking the projects of his enemies. His first object was to ascertain the death of the real duke of York, and to confirm the opinion that had always prevailed with regard to that event. Five persons had been employed by Richard in the murder of his nephews, or could give evidence with regard to it; Sir James Tyrrel, to whom he had committed the government of the Tower for that purpose, and who had seen the dead princes; Forrest, Dighton, and Slater, who perpetrated the crime; and the priest who buried the bodies. Tyrrel and Dighton alone were alive, and they agreed in the same story; but as the priest was dead, and as the bodies were supposed to have been removed by Richard’s orders from the place where they were first interred, and could not now be found, it was not in Henry’s power to put the fact, so much as he wished, beyond all doubt and controversy.
