With these views, gay and winsome though she was, it was not long before Mary was at issue with her dour Protestant subjects and their spokesman, John Knox. It was hoped by her brother, James Stuart (Murray), and Secretary Lethington that a _modus vivendi_ might be found by persuading Elizabeth to secure to Mary the English succession in case she herself died childless, on the undertaking of Mary that her marriage and policy should be dictated by England; but it was not Elizabeth's plan to pledge the future of England, and her nimble evasiveness drove the Scottish statesmen to despair. Brawls and bitterness grew in Mary's court around the Catholicism of the queen, and English money and intrigue were freely lavished to set Scotland by the ears. Half the nobles were disaffected, and Murray and Lethington, having failed to secure Scottish interests by moderate counsels and the conciliation of Elizabeth, were forced to take a strong course. Of foreign suitors Mary had many, some promoted by the Protestants, some by the Pope and the Guises, while the Catholics of England were secretly intriguing to force Elizabeth's hand by arranging Mary's marriage with young Henry Stuart, Lord Darnley, eldest son of Margaret, Countess of Lennox, niece of Henry VIII., who lived at Elizabeth's court. Cecil's spies were everywhere, and the plot was soon known and stopped by Elizabeth, violently angry with her kinswoman for listening to such a scheme. But Murray and Lethington, in desperation, were aiming at higher game even than this. They were Protestant, they had tried their best to win Elizabeth's recognition; but they were Scotsmen first, and if their country was to be independent it must have a great ally behind it. France was out of the question while the Guises were in the shade and Catharine was queen-mother. So the ministers of Mary turned their eyes to the Protestant heir of the Catholic king. Elizabeth soon heard of this, too, and suddenly pretended to be in favour of the Darnley match for Mary, while she developed the most cordial friendship for Mary herself; for the Guises had again become paramount in France, and Elizabeth could not afford to flout all the Catholic interests at once. That danger soon passed, for the Huguenots flew to arms, and Guise was murdered, Mary losing thus her principal prop abroad. And Lethington now pushed vigorously what seemed to be Scotland's only chance of safety--the marriage of Mary with the semi-idiot heir of Spain. The English Catholics were drawn into the plot. "Only let Mary marry the heir of Spain, and we will salute her as our leader," said they. But Elizabeth soon gained wind of it, as usual, and was ready with her antidote--a most extraordinary one--the proposal that Mary should wed her own lover, Lord Robert Dudley, with the assurance of the English succession after Elizabeth's death without issue. It was a mere feint, of course, but it divided Scotland, and unsettled Mary herself.
