Another historian who lived in those days, the Rev. Laurence Eachard, Archdeacon of Stowe, states Dr. Tonge was "a man of letters, and had a prolific head filled with all the Romish plots and conspiracies since the reformation." According to this author, Tonge took Oates into his house, provided him with lodging, diet, and clothes; and when the latter complained he knew not where to get bread, the rector told him "he would put him in a way." After this, finding Oates a man of great ingenuity and cunning, "he persuaded him," says Archdeacon Eachard, "to insinuate himself among the papists, and get particular acquaintance with them; which being effected, he let him understand that there had been several plots in England to bring in popery, and that if he would go beyond sea among the Jesuits, and strictly observe their ways, it was possible there might be one at present; and if he could make that out, it would be his preferment for ever; but, however, if he could get their names, and some information from the papists, it would be very easy to rouse people with the fears of popery."
Hungering for gold, and thirsting for notoriety, Oates quickly agreed to the scheme laid before him. Accordingly he became acquainted with, and was received into the Catholic Church by, Father Berry, a Jesuit, and in May, 1677, was sent by the Jesuits to study in one of their seminaries, situated in Valladolid, in Spain. Oates, however, though he had proved himself an excellent actor, could not overcome his evil propensities, and before seven months had passed, he was expelled from the monastery.
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 IPSO FACTO 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 be 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.
Bewildered by such intelligence, yet suspicious of its veracity, the king ordered Kirby to summon his informant that evening by eight o'clock. When that hour came his majesty repaired to the Red Room, and there met Dr. Tonge, who delivered his narrative into his hands. The rector was convinced the great moment he had so long awaited, in which he would behold the monarch aroused to a sense of his danger, had arrived. He was doomed to bitter disappointment. His majesty coolly took the narrative, and without opening it, said it should be examined into. On this Tonge begged it might be kept safe and secret, "lest the full discovery should otherwise be prevented and his life endangered." The monarch replied that, before starting with the court to-morrow for Windsor, he would place it in the hands of one he could trust, and who would answer for its safety. He then bade him attend on the Lord Treasurer Danby next morning.
In obedience to this command, Tonge waited on his lordship at the appointed time, and by the character of his replies helped to develop his story of the plot. When asked if the document he had given his majesty was the original of the deponent, Tonge admitted it was in his own handwriting. On this, Lord Danby expressed a desire to see the original, and likewise become acquainted with its author. Nothing abashed, the rector replied the manuscript was in his house, and accounted for its possession by stating that, singularly enough, it had been thrust under his door—he did not know by whom, but fancied it must be by one who, some time before, had discussed with him on the subject of this conspiracy. Whereon his lordship asked him if he knew the man, and was answered he did not, but he had seen him lately two or three times in the streets, and it was likely he should see him soon again.
Being next questioned as to whether he had any knowledge of Honest William, or Pickering, the villains who sought the king's life, he answered he had not. Immediately, however, he remembered it was their habit to walk in St. James's Park, and said, if any man was appointed to keep him company, he was almost certain he would have opportunities of letting that person see these abominable wretches. Finally, Lord Danby asked him if he knew where they dwelt, for it was his duty to have them arrested at once; but of their abode Tonge was completely ignorant, though he was hopeful he should speedily be able to obtain the required information.
