the service of the Regent, is henceforth the central figure of every
intrigue. Witty, eloquent, subtle, he was indispensable, and he had one
great ruling motive, to unite the crowns and peoples of England and
Scotland. Unfortunately he loved the crafty exercise of his dominion
over men's minds for its own sake, and when, in some inscrutable way, he
entered the clumsy plot to murder Darnley, and knew that Mary could prove
his guilt, his shiftings and changes puzzle historians. In Scotland he

Scottish attack on the walls; but on June 16 the Regent made a good end,
in peace with all men. She saw Chatelherault, James Stewart, and the
Earl Marischal; she listened patiently to the preacher Willock; she bade
