This tool of the court of St. Germains came over from France, in company with John Murray, who was sent to watch his proceedings, and also to aid his object in procuring the promises of the most distinguished Highland chieftains to the furtherance of the projected invasion of England. The assistance of Captain Murray was conjoined on this occasion, the fidelity of that gentleman having been ascertained by the court of St. Germains; whilst there existed not a human being who did not instinctively distrust Beaufort: to Mary of Modena, who far more ardently desired the restoration of the Stuarts than her consort James, he was peculiarly obnoxious. The exiled Queen's fears proved well founded, for no sooner had Beaufort landed in England, than he formed the scheme of converting this secret enterprise into a means of obtaining reward and protection from the Duke of Argyle, whose mediation with the Duke of Queensbury he required for private reasons; he therefore notified his arrival to Argyle, who had been his early and hereditary friend, offering at the same time to make great disclosures, if he had previous assurances of remuneration. Such is the account of most impartial writers, and more especially of those who lean to the Whig party: but, by the Jacobites, the very existence of a conspiracy to invade England at this time was denied, and the whole affair was declared to be a scheme of the Duke of Queensbury's to undermine the reputation of the Cavaliers, and "to find a pretence to vent his wrath, and execute his malice against those who thwarted his arbitrary designs," for the completion of a treaty of union between Scotland and England, which had been in contemplation ever since the days of William the Third.[22] After much deliberation the Duke of Queensbury was induced to have several communications with Fraser of Beaufort, and to listen to the information which he gave, all of which the Duke transmitted to Queen Anne, although he concealed the name of his informant. In consequence of Fraser's disclosures, several persons coming from France to England were apprehended on suspicion of being engaged in the Pretender's service, and an universal alarm was spread, as well as a distrust of the motives and proceedings of Queensbury, who thus acted upon the intelligence of an avowed spy, and noted outlaw, like Fraser. A temporary loss of Queensbury's political sway in Scotland was the result, and a consequent increase of power to the Squadrone Volante.
