Mary dressed her young cousin in a velvet bonnet, because the queen wanted the girl out of her French fashions. Her help survives in other people's letters. Later writers gave her another young woman's translations instead.
She sent Anne Boleyn a monkey. She sent Jane Seymour quails. She housed Anne of Cleves for a fortnight. She put her own daughter in the path of the king. None of it was kindness. All of it was survival. For seven years it worked. Then it didn't.
