By 1528, only four years into their marriage, the couple's relationship had broken down irretrievably. Northumberland suspected his wife of spying on him for Norfolk, while her father worried that the young husband was abusing her and might even poison her. Northumberland was outraged at Shrewsbury's suspicions and refused to permit his father-in-law's servants to see or speak to his wife. When the countess's brother-in-law, William, Lord Dacre, asked the Duke of Norfolk to defend her, Northumberland told Norfolk that he, Northumberland, would never see her again as long as he lived. The couple may have separated shortly thereafter, at least temporarily, since Mary delivered a stillborn child at her father's home in April 1529. In 1532, Mary accused her husband of a precontract (i.e. betrothal with legal force) with Anne Boleyn. She confided her alleged grievance to her father, who then mentioned the matter to Thomas Howard, 3rd Duke of Norfolk. Anne Boleyn, consulted, ordered an inquiry. Northumberland denied the accusation on oath.
