After some search, the duchess found a stripling whom she thought had all the qualities requisite to personate the unfortunate prince. This youth is described as being "of visage beautiful, of countenance majestical, of wit subtile and crafty; in education pregnant, in languages skilful; a lad, in short, of a fine shape, bewitching behaviour, and very audacious." The name of this admirable prodigy was Peterkin, or Perkin Warbeck, and he was the son of John Warbeck, a renegade Jew of Tournay. Some writers, and among others Lord Bacon, suggest that he had certain grounds for his pretensions to royal descent, and hint that King Edward, in the course of his amorous adventures, had been intimate with Catherine de Faro, Warbeck's wife; and Bacon says "it was pretty extraordinary, or at least very suspicious, that so wanton a prince should become gossip in so mean a house." But be this as it may, the lad was both handsome and crafty, and was well suited for the part which he was destined to play.
Some years after his birth, the elder Warbeck returned to Tournay, carrying the child with him; but Perkin did not long remain in the paternal domicile, but by different accidents was carried from place to place, until his birth and fortunes became difficult to trace by the most diligent inquiry. No better tool could have been found for the ambitious Duchess of Burgundy; and when he was brought to her palace, she at once set herself to instruct him thoroughly with respect to the person whom he was to represent. She so often described to him the features, figures, and peculiarities of his deceased--or presumedly deceased--parents, Edward IV. and his queen, and informed him so minutely of all circumstances relating to the family history, that in a short time he was able to talk as familiarly of the court of his pretended father as the real Duke of York could have done. She took especial care to warn him against certain leading questions which might be put to him, and to render him perfect in his narration of the occurrences which took place while he was in sanctuary with the queen, and particularly to be consistent in repeating the story of his escape from his executioners. After he had learnt his lesson thoroughly, he was despatched under the care of Lady Brampton to Portugal, there to wait till the fitting time arrived for his presentation to the English people.
