My dear brother
I am very sorry that your marriage has failed.
Now you must fight for the kingdom of our mother.
You are a great king and people of Navarre loves you.
I think that you should look for a new wife, a good woman,that she to be a good mother for Magdalene and Joanna and that she can give you a son.
I think that Lady Carmen de Salinas would be a good wife to you.
She descends from Foix family, our mother's family, she is educated, kind, noble, and her niece is the wife of the Duke of Suffolk, close friend of King Henry VIII.
With Love
Your sister, Quiteria de Albret, princess of Navarre and Duchess of Teruel.
