On Oates's return, he further stoked Tonge's paranoia with stories of Jesuit conspiracies, including a plot against a feared anti-Catholic author – Tonge himself. He was at least sufficiently impressed to ask the
Lord Treasurer,
Danby, to investigate. Danby agreed that the matter deserved inquiry, despite opposition from another leading minister, Sir
Joseph Williamson, who knew Tonge and believed he was insane. Tonge then took two crucial decisions: firstly he persuaded Oates to swear to the truth of his allegations before the much-respected magistrate, Sir
Edmund Berry Godfrey. Secondly, he persuaded the King and Danby to put the matter before a full meeting of the
Privy Council. At the hearing, Tonge himself made a bad impression: his reputation for eccentricity, if not outright madness, was well known, and he was "altogether smiled at ". Oates, on the other hand, gave a superb performance: so detailed and convincing was his story that the Council ordered the arrest of all the leading Jesuits accused, as well as
Edward Coleman, former secretary to the
Duke of York (later
James II & VII.) The news of this, followed by the murder of Godfrey, caused public hysteria to erupt. During the years of the Plot, Tonge was a secondary figure: he did not claim to have any first-hand knowledge of the Plot itself, and was never a witness in any of the Plot trials. However, a generous allowance from the Crown allowed him to live out his last years in comfort at
Whitehall; the Crown even paid for his funeral. ==Reputation ==
