The _Franciscan_ wanting somebody whom he could trust his Secret to, and by whom he might give the Marquiss _Daiamonti_ a strict Account of his Negotiation, cast his eyes upon the _Castilian_, who seem'd very much attach'd to the Interest of the Duke of _Medina_. To this end he detain'd the _Spaniard_ some time, pretending that he could not as yet procure him a Passport, tho his Intent was to observe him, and see whether or not he was a Person fit to be entrusted. Their being frequently together begat an intimate Acquaintance, which they both mutually desir'd; the Monk, that he might engage the _Spaniard_ to serve him; and the _Spaniard_, that he might make himself Master of the Monk's Secret. This holy Man, like the rest of his Brethren, puff'd up with Vanity, could not forbear one day telling his Friend, that he would not long see him in that Garb in which he was, that he had a Bishoprick promis'd him, and that he did not despair of obtaining the _Roman_ Purple. _Sancho_, to make him prattle the faster, pretended that he did not believe a word of what he said. The Fryar laugh'd at his Incredulity: "And I suppose, _continued he_, you would not believe me neither, if I should tell you, that the Duke of _Medina_ will shortly be a King." The other, to get the Secret quite out of him, urg'd the Impossibility of it; upon which the Monk told him the whole Story: That _Andalusia_ must in a little time acknowledge the Duke for their Sovereign: That the Marquiss _Daiamonti_, who had also discover'd the _Spanish_ Plot to the King of _Portugal_, was the chief Negotiator and Instrument of this intended Revolution: That he should shortly see strange Alterations in _Spain_, and that he had now an opportunity of making his Fortune only by being secret, and taking care to deliver some Letters from him to the Duke and Marquiss. _Sancho_, well pleas'd at the Discovery of this Secret, which he had long labour'd to get out of him, renew'd his Protestations of Fidelity and Secrecy, and his Offers of Service; and having taken _Velasco_'s Letters, told him, that he should be proud of the Opportunity of serving the Prince, and hoped that he should be thought worthy of the Honour of bringing him an Answer. Upon this the _Castilian_ set out for _Andalusia_, but was no sooner got into the _Spanish_ Territories, than he took the _Madrid_ Road; and as soon as he arriv'd, went strait to the Minister's House, and sent him word that _Sancho_, Pay-Master of the Army in _Portugal_, was just escaped out of Prison, where he had been confin'd by the Usurper, and had some important Business to communicate to him. It was a very hard matter to gain Access to _Olivarez_, who had his set Hours of granting Audience, and at which time he sent word the Pay-Master must return. Enrag'd at this Refusal, _Sancho_ cry'd he must, he would speak to him; that his Business was no Trifle, but the Safety of the Kingdom depended on its being immediately reveal'd.
