Why is Her Door Locked?

November 1907: Everyone's been concerned about Mrs. Bridges, who's been despondent ever since Emily's suicide, but when they discover she took a baby from his pram when his mother wasn't looking, and brought him home with her, they realise she's suffering from a mental breakdown. Hoping to keep the incident quiet and protect everyone's reputations, the Bellamys return the baby to his parents and offer compensation, but refuse to divulge Mrs. Bridges' identity. The father, furious that they consider themselves above the law, has Mrs. Bridges arrested and during her hearing, Hudson makes an extraordinary gesture he hopes will keep her out of prison.
