At this point, Henry VII faced the challenge of avoiding the obligation to return her 200,000-ducat dowry, half of which he had not yet received, to her father, as required by her marriage contract should she return home. Following the death of Queen Elizabeth in February 1503, there were rumours of a potential marriage between Catherine and King Henry; such rumours were, however, unsubstantiated. It was agreed that Catherine would marry Henry VII's second son, Henry, Duke of York, who was five years younger than she was. The death of Catherine's mother, however, meant that her "value" in the marriage market decreased. Castile was a much larger kingdom than Aragon, and it was inherited by Catherine's elder sister, Joanna. Ostensibly, the marriage was delayed until Henry was old enough, but Ferdinand II procrastinated so much over payment of the remainder of Catherine's dowry that it became doubtful that the marriage would take place. She lived as a virtual prisoner at Durham House in London. Some of the letters she wrote to her father complaining of her treatment have survived. In one of these letters she tells him that "I choose what I believe, and say nothing. For I am not as simple as I may seem." She had little money and struggled to cope, as she had to support her ladies-in-waiting as well as herself. In 1507 she served as the Spanish ambassador to England, the first female ambassador in European history. While Henry VII and his counsellors expected her to be easily manipulated, Catherine went on to prove them wrong.
