The first thought of the conspirators was that their design had been detected. But they were soon reassured. It was given out that the weather had kept the King at home; and indeed the day was cold and stormy. There was no sign of agitation at the palace. No extraordinary precaution was taken. No arrest was made. No ominous whisper was heard at the coffeehouses. The delay was vexatious; but Saturday the twenty-second would do as well.
But, before Saturday the twenty-second arrived, a third informer, De la Rue, had presented himself at the palace. His way of life did not entitle him to much respect; but his story agreed so exactly with what had been said by Fisher and Pendergrass that even William began to believe that there was real danger.
Very late in the evening of Friday the twenty-first, Pendergrass, who had as yet disclosed much less than either of the other informers, but whose single word was worth much more than their joint oath, was sent for to the royal closet. The faithful Portland and the gallant Cutts were the only persons who witnessed the singular interview between the King and his generous enemy. William, with courtesy and animation which he rarely showed, but which he never showed without making a deep impression, urged Pendergrass to speak out. "You are a man of true probity and honour; I am deeply obliged to you; but you must feel that the same considerations which have induced you to tell us so much ought to induce you to tell us something more. The cautions which you have as yet given can only make me suspect every body that comes near me. They are sufficient to embitter my life, but not sufficient to preserve it. You must let me know the names of these men." During more than half an hour the King continued to entreat and Pendergrass to refuse. At last Pendergrass said that he would give the information which was required, if he could be assured that it would be used only for the prevention of the crime, and not for the destruction of the criminals. "I give you my word of honour," said William, "that your evidence shall not be used against any person without your own free consent." It was long past midnight when Pendergrass wrote down the names of the chief conspirators.
While these things were passing at Kensington, a large party of the assassins were revelling at a Jacobite tavern in Maiden Lane.
Here they received their final orders for the morrow. "Tomorrow or never," said King. "Tomorrow, boys," cried Cassels with a curse, "we shall have the plunder of the field." The morrow came.
