Not a line of treasonable matter was to be found anywhere.

To the certificates upon Mr.Caryll the searcher made the mistake of paying but little heed in view of their nature.
But if there were no proofs of plots and treasonable dealings, there was, at least, abundant proof of Sir Richard's identity, and Mr.Green appropriated these against any awkward inquiries touching the manner in which the baronet had met his death.
Of such inquiries, however, there were none.

It was formally sworn to Lord Carteret by Green and his men that the secretary's messenger, Jerry--the fellow owned no surname--had shot Sir Richard in self-defence, when Sir Richard had produced firearms upon being arrested on a charge of high treason, for which they held the secretary's own warrant.
At first Lord Carteret considered it a thousand pities that they should not have contrived matters better so as to take Sir Richard alive; but upon reflection he was careful not to exaggerate to himself the loss occasioned by his death, for Sir Richard, after all, was a notoriously stubborn man, not in the least likely to have made any avowals worth having.

So that his trial, whilst probably resulting sterile of such results as the government could desire, would have given publicity to the matter of a plot that was hatching; and such publicity at a time of so much unrest was the last thing the government desired.

Where Jacobitism was concerned, Lord Carteret had the wise discretion to proceed with the extremest caution.
