Esther Summerson
Esther narrates half the novel and holds the domestic world together. She's an orphan who doesn't know her origins, and her search for identity runs underneath everything she does. She's capable and warm, but Dickens also shows how much she has internalized the shame her aunt put on her.
Richard Carstone
Richard is the novel's clearest victim of the lawsuit. He's not weak exactly, but he's young and hopeful in the wrong direction. His fixation on Jarndyce and Jarndyce replaces every other ambition he has, and it kills him.
Lady Dedlock
Lady Dedlock is the novel's tragic figure. She's powerful, composed, and completely trapped by her past. Her secret drives the thriller plot, and her death at Hawdon's grave closes it. She can't outrun what she buried.
John Jarndyce
Jarndyce is the novel's moral center. He refuses to engage with the lawsuit, takes in three wards, and eventually steps aside so Esther can be happy. He's one of the few characters in the novel who acts well consistently.
Tulkinghorn
Tulkinghorn is the lawyer who collects secrets. He threatens Lady Dedlock not for money but for control. He's the novel's clearest example of how legal and social power can be used to crush people without technically breaking any rules.
Inspector Bucket
Bucket is one of the first detectives in English fiction. He's shrewd, relentless, and surprisingly humane. He solves Tulkinghorn's murder and leads the chase for Lady Dedlock, but he can't save her.
Jo
Jo is a homeless crossing-sweeper who can't read and has no rights. He's connected to Hawdon and spreads the fever that scars Esther. Dickens uses him to make the novel's most direct argument about poverty and social neglect.
Harold Skimpole
Skimpole presents himself as a childlike innocent who doesn't understand money or responsibility. Dickens gradually reveals this is a performance. He's selfish and parasitic, and he betrays Jo for a small payment.
Ada Clare
Ada loves Richard and marries him in secret, hoping to help him. She can't stop his decline. After his death she returns to Bleak House with their child. She's loyal and good, but the novel shows that loyalty alone can't fix what the lawsuit does.
Allan Woodcourt
Woodcourt is the doctor who loves Esther. He's decent and capable, and he makes clear that her smallpox scars don't change how he sees her. He ends up with Esther after Jarndyce steps aside.
