The first attempt was made on Porter.  Clancy contrived to fall in with him at a tavern, threw out significant hints, and, finding that those hints were favourably received, opened a regular negotiation.  The terms offered were alluring; three hundred guineas down, three hundred more as soon as the witness should be beyond sea, a handsome annuity for life, a free pardon from King James, and a secure retreat in France.  Porter seemed inclined, and perhaps was really inclined, to consent.  He said that he still was what he had been, that he was at heart attached to the good cause, but that he had been tried beyond his strength.  Life was sweet.  It was easy for men who had never been in danger to say that none but a villain would save himself by hanging his associates; but a few hours in Newgate, with the near prospect of a journey on a sledge to Tyburn, would teach such boasters to be more charitable.  After repeatedly conferring with Clancy, Porter was introduced to Fenwick’s wife, Lady Mary, a sister of the Earl of Carlisle.  Every thing was soon settled.  Donelagh made the arrangements for the flight.  A boat was in waiting.  The letters which were to secure to the fugitive the protection of King James were prepared by Fenwick.  The hour and place were fixed at which Porter was to receive the first instalment of the promised reward.  But his heart misgave him.  He had, in truth, gone such lengths that it would have been madness in him to turn back.  He had sent Charnock, King, Keyes, Friend, Parkyns, Rookwood, Cranburne, to the gallows.  It was impossible that such a Judas could ever be really forgiven.  In France, among the friends and comrades of those whom he had destroyed, his life would not be worth one day’s purchase.  No pardon under the Great Seal would avert the stroke of the avenger of blood.  Nay, who could say that the bribe now offered was not a bait intended to lure the victim to the place where a terrible doom awaited him?  Porter resolved to be true to that government under which alone he could be safe; he carried to Whitehall information of the whole intrigue; and he received full instructions from the ministers.  On the eve of the day fixed for his departure he had a farewell meeting with Clancy at a tavern.  Three hundred guineas were counted out on the table.  Porter pocketed them, and gave a signal.  Instantly several messengers from the office of the Secretary of State rushed into the room, and produced a warrant.  The unlucky barber was carried off to prison, tried for his offence, convicted and pilloried.727

This mishap made Fenwick’s situation more perilous than ever.  At the next sessions for the City of London a bill of indictment against him, for high treason, was laid before the grand jury.  Porter and Goodman appeared as witnesses for the Crown; and the bill was found.  Fenwick now thought that it was high time to steal away to the Continent.  Arrangements were made for his passage.  He quitted his hiding place, and repaired to Romney Marsh.
