Sheppard, having conceived the idea that it would be a praiseworthy action to kill the king, wrote a letter, which he intended for a nonjuring minister of the name of Leake; but, mistaking the spelling, he directed it "To the Rev. Mr. Heath." The letter was in the following terms:-- "Sir,--From the many discontents visible throughout this kingdom, I infer that if the prince now reigning could be by death removed, our king being here, he might be settled on his throne without much loss of blood. For the more ready effecting of this, I propose that, if any gentleman will pay for my passage into Italy, and if our friends will entrust one so young with letters of invitation to his majesty, I will, on his arrival, smite the usurper in his palace. In this confusion, if sufficient forces may be raised, his majesty may appear; if not, he may retreat or conceal himself till a fitter opportunity. Neither is it presumptuous to hope that this may succeed, if we consider how easy it is to cut the thread of human life; how great confusion the death of a prince occasions in the most peaceful nation; and how mutinous the people are, how desirous of a change. But we will suppose the worst--that I am seized, and by torture examined. Now, that this may endanger none but myself, it will be necessary that the gentlemen who defray my charges to Italy leave England before my departure; that I be ignorant of his majesty's abode; that I lodge with some whig; that you abscond; and that this be communicated to none. But, be the event as it will, I can expect nothing less than a most cruel death; which, that I may the better support, it will be requisite that, from my arrival till the attempt, I every day receive the Holy Sacrament from one who shall be ignorant of the design. "JAMES SHEPPARD." Having carried it to Mr. Leake's house, he called again for an answer, but he was apprehended, and carried before Sir John Fryer, a magistrate. When he was brought to his trial, he behaved in the most firm and composed manner; and, after the evidence was given, and the jury had found him guilty of high treason, he was asked why sentence should not be passed on him according to law, when he said "He could not hope for mercy from a prince whom he would not own." The Recorder then proceeded to pass sentence on him; in pursuance of which, he was executed at Tyburn on the 17th March, 1718. He was attended by a nonjuring clergyman up to the time of his execution, between whom and the ordinary the most indecent disputes arose, extending even up to the time of his arriving at the scaffold, when the latter quitted the field and left the other to instruct and pray with the malefactor as he might think proper.
