"My well-beloved sister," answered the queen, "gladly would I show to you all affection if I were but sure that your heart was turned toward me and toward that which is not only my dearest wish but is for the salvation of your own soul." "I have but followed the belief in which I was brought up," said Elizabeth. "Such books as my father approved have been my reading. I will study others if you will, and it may be that my mind will be opened to perceive truth in doctrines wherein I had not thought it to lie." "It will be a pleasure to my chaplain to choose for you those that are of such quality as to lead a truly inquiring heart into the way of right." "Yet another kindness do I beg of you, my queen and sister," said Elizabeth. "I have listened to those whom I was told to hear. Will your Grace send to me some well-taught preacher to instruct me in the way wherein you would have me to walk? Never have I heard any learned doctor discourse in such wise as to show me where lay my error." Mary agreed, and a few days later the two sisters attended mass together. Elizabeth even wrote to the German emperor that she intended to have a Catholic chapel opened in her own house, and asked his permission to purchase in Flanders a cross, chalice, and such ornaments as would be needed. No one had much confidence in her sudden change of creed. Those Protestants who were discontented went on with their plots to make her queen, convinced none the less that once on the throne, she would restore the Protestant form of worship. The German emperor, who was Mary's chief adviser, urged that to insure the queen's safety Elizabeth ought to be imprisoned, or at any rate, so strictly guarded that she could do no harm. There was reason for his fears. Mary, Queen of Scots, would soon become the daughter-in-law of the French king, and while he was pretending to be a true friend to Elizabeth, he was in reality doing all in his power to make trouble between her and Mary. If Elizabeth could be led into some plot that would anger Mary and so could be shut out from the succession, his daughter-in-law might easily become queen of England as well as of Scotland. Vague rumors of discontent and plots came to the ears of Mary, and for some time she refused Elizabeth's request to be allowed to go to her own house.
