The interesting question arises how the monk was misled on these four points, when his information was so accurate, and so directly contradicts Morton, Polydore Virgil, and Fabyan, as regards the dates of events immediately preceding Richard's accession, and as regards the nature of his claim to the throne. Could Morton have been at his elbow? If he was, these errors would be explained, for they are the most telling points in Morton's case. We know that Morton was sent to Brecknock Castle, in the custody of the Duke of Buckingham, in August 1483. Later in the autumn he escaped, crossed England in disguise, and was concealed for some time in the fen country near Ely, before taking ship for Flanders. He even mentions his object in going there. 'If he were in the Isle of Ely,' he told Buckingham, 'he could make many {178} friends to further the enterprise.'[16] He went there to plot and intrigue. The secluded Abbey of Croyland is a likely asylum for Morton to have selected as a place of concealment. A political bishop who had been a principal actor in the recent events would be a Godsend to the chronicling monk; while the intriguer would be in his element, sowing the first seeds of his future crop of calumny. The second Croyland monk would be as clay in the potter's hand. He gives us a striking instance of his gossiping credulity. He had been told that the King's niece, Elizabeth, once appeared at Court in a dress similar to that of the Queen. Instead of the obvious deduction that Queen Anne had kindly provided the girl with a dress like her own, we are treated to dark hints about a rival who was to supplant the Queen, and modern historians have taken the old monk's nonsense in all seriousness. Morton would have found such a man quite ready to accept without further inquiry any statement he might make, and to be the channel of any rumour he chose to spread. Such are the witnesses arrayed against the last Plantagenet King by his Tudor successors. It will be our business to test the value of their testimony. They had it all their own way. No one was allowed to answer them. For those who knew the truth it was a choice between silence and ruin. The accused had no counsel. Whether the Tudor writers are trustworthy or not, there can be no question that, aided by these advantages, they served their employers well. They have completely succeeded in their object. They have blackened the memory of King Richard III. for all time.
