"Whereas, the late Earl of Argyle is, by the providence of God, fallen into our power, it is our will and pleasure that you take all ways to know from him those things which concern our government most, as his assisters with men, arms, and money, his associates and correspondents, his designs, etc. But this must be done so as no time may be lost in bringing him to condign punishment, by causing him to be demeaned as a traitor, within the space of three days after this shall come to your hands, an account of which, with what he shall confess, you shall send immediately to us or our secretaries, for doing which this shall be your warrant."
