In another letter to Escovedo, Perez enlarged upon the impropriety, the impossibility of Don John's leaving the Netherlands at that time. The King was so resolute upon that point, he said, that 'twas out of the question to suggest the matter. "We should, by so doing, only lose all credit with him in other things. You know what a terrible man he is; if he should once suspect us of having a private end in view, we should entirely miss our mark." Especially the secretary was made acquainted with the enormous error which would be committed by Don John in leaving his post. Perez "had ventured into the water" upon the subject, he said, by praising the Governor warmly to his Majesty. The King had responded by a hearty eulogium, adding that the greatest comfort in having such a brother was, that he might be where his Majesty could not be. Therefore, it was out of the question for Don John to leave the provinces. The greatest tact was necessary, urged Perez, in dealing with the King. If he should once "suspect that we have a private purpose, we are lost, and no Demosthenes or Cicero would be able to influence him afterwards." Perez begged that his ardent attachment to Don John might be represented in the strongest colors to that high personage, who was to be assured that every effort would be made to place him at the head of affairs in Spain, according to the suggestion of Escovedo. "It would never do, however," he continued, "to let our man see that we desire it, for then we should never succeed. The only way to conquer him is to make him believe that things are going on as he wishes, not as his Highness may desire, and that we have none of us any will but the King's." Upon this passage the "terrible man" made a brief annotation: "this paragraph does admirably," he said, adding, with characteristic tautology, "and what you say in it is also excellent."
