So Sir Walter Walshe was sent with a warrant to the Earl of Northumberland, and arrived as Wolsey was busied at Cawood with the preliminaries of his installation. On 4th November, when Wolsey had retired from dinner and was sitting in his own room over his dessert, the Earl of Northumberland appeared, and demanded the keys of the castle from the porter. He entered the hall, and posted his servants to guard all the doors. Wolsey, in ignorance of what was in store for him, met Northumberland and offered him hospitality, expressing his delight at the unexpected visit. When they were alone the Earl, "trembling, said, with a very faint and soft voice, unto my lord, laying his hand upon his arm, 'My lord, I arrest you of high treason.'" For a time Wolsey stood speechless with astonishment, then he asked to see the warrant, which Northumberland had not brought with him. As he was speaking Sir Walter Walshe opened the door and thrust into the room the physician Agostino, whom he had made prisoner. Wolsey asked him about the warrant, and when he recognised him as one of the gentlemen of the king's privy chamber, he submitted to the royal commands without asking further for the production of the warrant. Then he delivered up his keys to Northumberland. Agostino was at once sent to London tied under a horse's belly--a mode of conveyance which was doubtless calculated to refresh his memory. When he arrived in London he was taken to the Duke of Norfolk's house, and showed himself ready to bear witness against Wolsey. "Since they have had the cardinal's physician in their hands," writes the imperial envoy, "they have found what they sought. Since he has been here he has lived in the Duke of Norfolk's house like a prince, and is singing the tune they wished." There was not the same need of haste in bringing Wolsey to London, for even with Agostino's help Norfolk was doubtful if the evidence against Wolsey would be sufficient to ensure his condemnation to death; and he did not wish to give Wolsey the opportunity of a trial when he might still be formidable. His imprisonment in the Tower at the royal pleasure would only bring him nearer to the king, who might at any moment make use of him as he threatened. Really, Norfolk was somewhat embarrassed at the success of his scheme; and Wolsey, in a conversation with Cavendish, showed a flash of his old greatness. "If I may come to my answer," he said, "I fear no man alive; for he liveth not upon the earth that shall look upon this face and shall be able to accuse me of any untruth; and that know my enemies full well, which will be an occasion that I shall not have indifferent justice, but they will rather seek some other sinister way to destroy me."
