The manner in which Richard the Third disposed of his nephews, Edward the Fifth and Richard, Duke of York, was so mysterious and secret, that it is not strange that it gave rise to many curious complications, the perplexities of which had to be suffered by his successor. Presuming the two young princes to have been put to death, the next male heir to the throne, upon the demise of Richard the Third, was Edward, Earl of Warwick, the son of the late Duke of Clarence. At one time, indeed, Richard had treated the boy as heir-apparent, but his jealousy becoming aroused, he had him detained as a prisoner in the manor-house of Sheriff Hutton, doubtless with a view of causing him to share ultimately the sad fate of his cousins. One of the earliest acts of Henry the Seventh, after the defeat and death of Richard at Bosworth Field, was to secure the person of the Earl of Warwick; he had the youthful captive brought up to London, from Yorkshire, and then the poor boy, "born to perpetual calamity," as Hall remarks, "was incontinent in the Tower of London put under safe and sure custody." The place of this unfortunate prince's durance, Henry's known character, and the apparently parallel case of his two cousins, quickly gave rise to the rumour that Edward had died suddenly. This intelligence corresponded with the projected schemes of a certain Richard Simon, a priest residing at Oxford. This man for some time past, if Bacon and other authorities are to be believed, had been educating a baker's son, Lambert Simnel by name, to play a daring and apparently hopeless part in his ambitious game, and the news of the Earl of Warwick's death afforded him the desired opportunity of taking the first step. The priest and his pupil, a lad of no small natural dignity and tact, proceeded to Ireland, and in November, 1486, landed at Dublin.
