A short time after his disappearance, Sidney received from him a strange communication. Penn begged for an interview, but insisted on a promise that he should be suffered to return unmolested to his hiding place. Sidney obtained the royal permission to make an appointment on these terms. Penn came to the rendezvous, and spoke at length in his own defence. He declared that he was a faithful subject of King William and Queen Mary, and that, if he knew of any design against them, he would discover it. Departing from his Yea and Nay, he protested, as in the presence of God, that he knew of no plot, and that he did not believe that there was any plot, unless the ambitious projects of the French government might be called plots. Sidney, amazed probably by hearing a person, who had such an abhorrence of lies that he would not use the common forms of civility, and such an abhorrence of oaths that he would not kiss the book in a court of justice, tell something very like a lie, and confirm it by something very like an oath, asked how, if there were really no plot, the letters and minutes which had been found on Ashton were to be explained. This question Penn evaded. "If," he said, "I could only see the King, I would confess every thing to him freely. I would tell him much that it would be important for him to know. It is only in that way that I can be of service to him. A witness for the Crown I cannot be for my conscience will not suffer me to be sworn." He assured Sidney that the most formidable enemies of the government were the discontented Whigs. "The Jacobites are not dangerous. There is not a man among them who has common understanding. Some persons who came over from Holland with the King are much more to be dreaded." It does not appear that Penn mentioned any names. He was suffered to depart in safety. No active search was made for him. He lay hid in London during some months, and then stole down to the coast of Sussex and made his escape to France. After about three years of wandering and lurking he, by the mediation of some eminent men, who overlooked his faults for the sake of his good qualities, made his peace with the government, and again ventured to resume his ministrations. The return which he made for the lenity with which he had been treated does not much raise his character. Scarcely had he again begun to harangue in public about the unlawfulness of war, when he sent a message earnestly exhorting James to make an immediate descent on England with thirty thousand men. [39]
