A thief of most infamous character, named Arnold Powel, being confined in Newgate, on a charge of having robbed a house in the neighbourhood of Golden Square of property to a great amount, was visited by Jonathan, who informed him that, in consideration of a sum of money, he would save his life; adding that if the proposal was rejected, he should inevitably die at Tyburn for the offence on account of which he was then imprisoned. The prisoner, however, not believing that it was in Wild's power to do him any injury, bade him defiance. He was brought to trial; but through a defect of evidence he was acquitted. Having gained intelligence that Powel had committed a burglary in the house of Mr. Eastlick, near Fleet Ditch, Wild caused that gentleman to prosecute the robber. Upon receiving information that a bill was found for the burglary, Powel sent for Wild, and a compromise was effected according to the terms which Wild himself had proposed, in consequence of which Powel was assured that his life should be preserved. Upon the approach of the sessions Wild informed the prosecutor that the first and second days would be employed in other trials; and as he was willing Mr. Eastlick should avoid attending with his witnesses longer than was necessary, he would give timely notice when Powel would be arraigned. But he contrived to have the prisoner put to the bar; and no persons appearing to prosecute, he was necessarily dismissed; and the court ordered Mr. Eastlick's recognisances to be estreated. Powel was ordered to remain in custody till the next sessions, there being another indictment against him; and Mr. Eastlick represented the behaviour of Wild to the court, who reprimanded him with great severity. Powel now put himself into a salivation, in order to avoid being brought to trial the next sessions; but, notwithstanding this stratagem, he was arraigned and convicted, and was executed on the 20th of March, 1717. At this time Wild quitted his apartments at Mrs. Seagoe's, and hired a house adjoining to the Coopers' Arms, on the opposite side of the Old Bailey. His unexampled villanies were now become an object of so much consequence, as to excite the particular attention of the legislature; and in the year 1718 an act was passed, deeming every person guilty of a capital offence who should accept a reward in consequence of restoring stolen effects without prosecuting the thief. It was the general opinion that this law would effectually suppress the iniquitous practices he had carried on; but, after some interruption to his proceedings, he devised means for evading it, which were for several years attended with success.
