Then, for the first time, the 'common fame' was ordered to spread the report that King Richard 'had put them under suer kepynge within the tower, in such wise that they never came abrode after,' and that 'King Richard put them unto secrete death.'[14] But Henry feared detection. The mother knew that this was false. If the boys were murdered in July 1486, that mother must soon have begun to feel uneasy. She was at Winchester with her daughter when her grandchild Arthur was born on September 20, 1486, and was present at the baptism. But she was in London in the autumn, and before many months her suspicions must have been aroused. She must be silenced. Consequently, in February 1487 'it was resolved that the Lady Elizabeth, wife of King Edward IV., should lose and forfeit all her lands and possessions because she had voluntarily submitted herself and her daughters {257} to the hands of King Richard. Whereat there was much wondering.'[15] She was ordered to reside in the nunnery of Bermondsey.[16] Once she was allowed to appear at Court on a State occasion.[17] The pretext for her detention was not the real motive, for Henry had made grants of manors and other property to his mother-in-law soon after his accession,[18] when her conduct with regard to King Richard was equally well known to him. The real reason was kept secret, as well it might be. Mr. Gairdner calls this proceeding 'a very mysterious decision taken about the Queen {258} Dowager.'[19] Very mysterious, indeed, on the assumption of Henry's innocence. But not so if the mother knew that her sons were alive when Richard fell, and could now obtain no tidings of them. If the boys ceased to live in July 1486, it was high time for Henry to silence the awkward questions of their mother in the following February. He did so by condemning her to life-long seclusion in a nunnery. Henry was terrified that a lady who knew some of his secrets, and probably suspected more, should be at large. In the end of the following year, and not till then, Henry's wife Elizabeth was at length crowned on November 25, 1487. The King and his mother beheld the ceremony from a stage, but there is no mention of the poor Queen's mother. [Sidenote: Polydore Virgil's story] Years passed on. Perkin Warbeck personated young Richard, and no one had such good reason as Henry for knowing that he was an impostor. But the tyrant dared not tell how he knew that Perkin was a 'feigned boy,' as he called him. At length, in 1502 or thereabouts, the first detailed story of the murder of the two princes was put forward, after the execution of Sir James Tyrrel. It may be considered as Henry's official statement, and was evidently communicated to his paid historian Polydore Virgil, in whose hands it took the following form:
