Read it through once

Grey was more ingenuous (it is not certain in what sense his majesty uses the term, since he does not refer to any discovery made by that lord), and never once begged his life. Short as this account is, it seems the only authentic one of those interviews. Bishop Kennet, who has been followed by most of the modern historians, relates, that "This unhappy captive, by the intercession of the queen dowager, was brought to the king's presence, and fell presently at his feet, and confessed he deserved to die; but conjured him, with tears in his eyes, not to use him with the severity of justice, and to grant him a life, which he would be ever ready to sacrifice for his service. He mentioned to him the example of several great princes, who had yielded to the impressions of clemency on the like occasions, and who had never afterwards repented of those acts of generosity and mercy; concluding, in a most pathetical manner, 'Remember, sir, I am your brother's son, and if you take my life, it is your own blood that you will shed.' The king asked him several questions, and made him sign a declaration that his father told him he was never married to his mother: and then said, he was sorry indeed for his misfortunes; but his crime was of too great a consequence to be left unpunished, and he must of necessity suffer for it. The queen is said to have insulted him in a very arrogant and unmerciful manner. So that when the duke saw there was nothing designed by this interview but to satisfy the queen's revenge, he rose up from his majesty's feet with a new air of bravery, and was carried back to the Tower."
