Elizabeth was all this time narrowly watching the progress of affairs in Scotland. Murray's restoration to favour pleased her much; and, to reconcile Morton and his friends to the failure of their plots, she secretly countenanced and protected them. With her usual duplicity, however, she sent to Edinburgh Henry Killigrew, to congratulate Mary on her late escape, and to assure her that she would give directions to remove Morton out of England. She likewise recalled Randolph, of whose seditious practices Mary had complained; but, as if to be even with the Scottish Queen, she commanded Killigrew to demand the reason why a certain person of the name of Ruxby, a rebel and a Papist, had been protected in Scotland? It would have been better for Elizabeth had she allowed this subject to rest. Though Ruxby feigned himself a refugee from England on account of religion, he had in reality been privately sent to Scotland by Elizabeth herself, and her Secretary Cecil. The object of his mission was to find out whether Mary carried on any secret correspondence with the English Catholics. For this purpose, he was to pretend that he was a zealous supporter of her right and title to the crown of England; and that he had some influence with the English Catholics, all of whom, he was to assert, thought as he did. Having thus ingratiated himself with Mary, he was immediately to betray any discoveries he might make to Cecil. The scheme was ingeniously enough contrived; coming as an avowed enemy to Elizabeth, and she herself actually supplying credentials to that effect, no suspicion was for some time entertained of his real designs. That he was able to learn any thing which could afford the English Queen reasonable ground of offence, is not likely; for though several communications in cipher passed between him and Cecil, their contents were never made public. Shortly before Killigrew's arrival, Ruxby's real character had been accidentally discovered; and when the ambassador, more for the sake of aiding than of hindering the spy in the prosecution of his object, made a _pro forma_ request that he should not be harboured any longer, Mary instantly ordered him to be apprehended, and all his writings and ciphers to be seized and examined. The indubitable evidence which they afforded of Elizabeth's systematic cunning, forced a smile from Mary, and might have brought a blush to the cheek of her rival. The Queen of Scots, however, did not condescend to give any utterance to the feelings which this affair must have inspired; and nothing further is known of Elizabeth's disgraced and detected minion.[140]
