Angus prolonged his outrages on the Scottish border till 1529, when he entered England as a subsidized mischief-maker against Scotland.
"Gaunab was at first a ghost, a mischief-maker and evil-doer " (op. cit.
I know he would never lend himself to any false tricks, even if they came from the `great mischief-maker himself.'"
He was disliked by the barons, who nicknamed him Flambard in reference to his talents as a mischief-maker; but he acquired the reputation of an acute financier and appears to have played an important part in the compilation of the Domesday survey.
