It is, indeed, certain, that as the king had thus unexpectedly left Newmarket, he was worse attended than usual; and Rumbald informed his confederates with regret what a fine opportunity was thus unfortunately lost.
Among the conspirators I have mentioned Keiling, a salter in London.
This man had been engaged in a bold measure, of arresting the mayor of London, at the suit of Papillon and Dubois, the outed sheriffs; and being liable to prosecution for that action, he thought it safest to purchase a pardon by revealing the conspiracy, in which he was deeply concerned.

He brought to Secretary Jenkins intelligence of the assassination plot; but as he was a single evidence, the secretary, whom many false plots had probably rendered incredulous, scrupled to issue warrants for the commitment of so great a number of persons.

Keiling, therefore, in order to fortify his testimony, engaged his brother in treasonable discourse with Goodenough, one of the conspirators; and Jenkins began now to give more attention to the intelligence.

The conspirators had got some hint of the danger in which they were involved, and all of them concealed themselves.

One person alone, of the name of Barber, an instrument-maker, was seized; and as his confession concurred in many particulars with Keiling's information, the affair seemed to be put out of all question; and a more diligent search was every where made after the conspirators.
West, the lawyer, and Colonel Rumsey, finding the perils to which they were exposed in endeavoring to escape, resolved to save their own lives at the expense of their companions; and they surrendered themselves with an intention of becoming evidence.
