Elizabeth thought she could avoid the latter danger without marriage at all, so she dexterously played with all her suitors, English and foreign, while strengthening her position and gaining popularity. Sometimes she swore she would never marry, and the next day would grow sentimental over the archduke, or flirted with Dudley--keeping them all in suspense and afraid of offending her. The French, having no marriageable prince of their own, supported Dudley, or any other English candidate whom they could use against Spain; whilst Dudley himself pretended to favour the archduke, till matters looked serious, and then found means of frustrating him, often to Elizabeth's rage, for she wished to play her own deep game unhampered. She knew she could always choke off the Austrian when she wished by making fresh religious demands. The English nobles were furious at Dudley's selfish manoeuvres to keep the queen unwed till he was free, and they planned to marry the queen to Arran, the next heir of Scotland. This looked promising for months, but Dudley and his sister, Lady Sidney, checked the plan. _II.--The Nine Years' Comedy_ In September, 1559, Dudley and his sister warmly took up the archduke's cause, and assured Quadra, the Spanish ambassador, that if the suitor would flatter the queen by coming to England on chance, she would marry him. But Elizabeth and Cecil, though they hinted much, would not clearly confirm Dudley's promise, and Philip and the emperor dared not expose the archduke to the risk of being repulsed. The English nobles, in good faith, urged the archduke's suit, and said that Dudley was plotting to kill his wife and marry the queen; but they and the Spanish ambassador were outwitted at every point by Elizabeth's diplomacy, and through 1559 and 1560 all the rivals were kept between hope and fear. Then, in September 1560, the long-predicted murder of Amy Robsart set Dudley free, and made the nobles and Cecil more anxious than ever that the archduke should be bold, take the risk, and come to England. The queen, to weaken the new friendship between France and Spain, herself again pretended eagerness for the Austrian's coming; but the trick was stale now, and neither Philip nor the emperor believed her. To checkmate Dudley the Protestants were actively urging the suit of Eric of Sweden, when, in January 1561, the former made a bold bid for Spanish support. He was, he said, quite innocent of his wife's death, and he promised Quadra that if the King of Spain would urge his (Dudley's) suit upon the queen, England should send envoys to the Council of Trent, receive a papal legate, and become practically Catholic. He might promise, but such a thing was impossible, and Cecil, when he learnt of the intrigue, promptly embroiled matters and spoilt the plan.
