Returning to England, he sought out Dr. Tonge, to whom he was unable to recount the secret of a single plot. Confident, however, that wicked schemes against the lives and properties of innocent protestants were being concocted by wily Jesuits, the fanatical divine urged Oates to present himself once more before them, bewail his misconduct, promise amendment, and seek readmission to their midst. Following his advice, Oates was again received by the Jesuits, and sent to their famous seminary at St. Omer's; where, though he had reached the age of thirty years, he was entered among the junior students. For six months he remained here, until his vices becoming noted, he was turned away in disgrace. Again he presented himself before the rector of St. Michael's, knowing as little of popish plots as he did on his previous return. But Tonge, though disappointed, was not disheartened; if no scheme existed, he would invent one which should startle the public, and save the nation. Such proposals as he made towards the accomplishment of this end were readily assented to by Oates, in whose breast wounded pride and bitter hate rankled deep. Therefore, after many consultations they resolved to draw up a "Narrative of a Horrid Plot." This was repeatedly changed and enlarged, until eventually it assumed the definite shape of a deposition, consisting of forty-three distinct articles, written with great formality and care, and embodying many shocking and criminal charges.
The narrative declared that in April, 1677, the deponent was employed to carry letters from the Jesuits in London to members of their order in Spain; these he broke open on the journey, and discovered that certain Jesuits had been sent into Scotland to encourage the presbyterians to rebel. Arrived in Valladolid, he heard one Armstrong, in a sermon delivered to students, charge his majesty with most foul and black-mouthed scandals, and use such irreverent, base expressions as no good subjects could repeat without horror. He then returned to England, and was soon after sent to St. Omer with fresh letters, in which was mentioned a design to stab or poison his majesty--Pere la Chaise, the French king's confessor, having placed ten thousand pounds at the disposal of the Jesuits that they might, by laying out such a sum, the more successfully accomplish this deed. While abroad the deponent had read many letters, relating to the execution of Charles II., the subverting of the present government, and the establishment of the Romish religion. Returning again to England, he became privy to a treaty with Sir George Wakeham, the queen's physician, to poison the king; and likewise with an agreement to shoot him, made between the Jesuits and two men, named Honest William and Pickering. He had heard a Jesuit preach a sermon to twelve persons of quality in disguise, in which he asserted "that protestants and other heretical princes were IPSOFACTO deposed because such; and that it was as lawful to destroy them as Oliver Cromwell or any other usurper." He also became aware that the dreadful fire had been managed by Strange, the provincial of the Jesuits, who employed eighty-six men in distributing seven hundred fire-balls to destroy the city; and that notwithstanding his vast expenses, he gained fourteen thousand pounds by plunder carried on during the general confusion, a box of jewels, consisting of a thousand carat weight of diamonds, being included in the robbery.
The document containing these remarkable statements was finished in August, 1678. It now remained to have it brought before the king or the council. Tonge was resolved this should he done in a manner best calculated to heighten the effect of their narrative;at the same time he was careful to guard the fact that he and Oates had an intimate knowledge of each other. Not knowing any one of interest at court, he sought out Christopher Kirby, a man employed in the king's laboratory, of whom he had some slight knowledge, and, pledging him to the strictest secrecy, showed him the "Narrative of the Horrid Plot," and besought his help in bringing it under the notice of his majesty in as private a manner as possible.
This aid was freely promised; and next day, the date being the 13th of August, when the monarch was about to take his usual airing in the park, Kirby drew near, and in a mysterious tone bade his majesty take care, for his enemies had a design against his life, which might be put into execution at any moment.
Startled by such words, the king asked him in what manner was it intended his life should be taken; to which he replied, "It might be by pistol; but that to give a more particular account of the matter, required greater privacy." The monarch, who quickly recovered his first surprise, resolved to take his usual exercise; and, subduing his curiosity, he bade Kirby attend him on his return from the park, and tell him what he knew of the subject.
When the time arrived, Kirby saw his majesty alone, and related to him in brief that two men waited but an opportunity to shoot him; and Sir George Wakeham had been hired to poison him; which news, he concluded, had been imparted to him by a worthy man living close at hand, who would attend his majesty's pleasure when that was manifested.
