Parliament declared her dead in 1474. She was forty-seven years old, in good health, and had approximately eighteen more years to live. The act required no evidence of death because her death was not the point. Her estates were the point. She was simply in the way of them.
She had already been married once for someone else's ambition, and widowed by someone else's war. The second time, the price of the wedding was that her own mother had to be treated in law as though she were already dead.
She gave birth on a ship off Calais in April 1470. The captain had refused to let them land. Her father was negotiating. The baby did not survive. The negotiations did.
Her father sold her to the enemy to settle a political debt. The enemy's son was dead within a year. The man she married next may have been in the room when it happened.
