In which Charles Dickens novel would you find the characters John Jarndyce and Mrs. Jellyby?

Bleak House is one of Charles Dickens's major novels, first published as a serial between March 1852 and September 1853. The novel has many characters and several sub-plots, and the story is told partly by the novel's heroine, Esther Summerson, and partly by a narrator. At the center of Bleak House is a long-running legal case, Jarndyce and Jarndyce, which came about because someone wrote several conflicting wills. Dickens uses this case to satirize the English judicial system, and he makes use of his earlier experiences as a law clerk and as a litigant seeking to enforce copyright on his earlier books.

John Jarndyce is an unwilling party in Jarndyce and Jarndyce, guardian of Richard, Ada, and Esther, and owner of Bleak House. Vladimir Nabokov called him "one of the best and kindest human beings ever described in a novel". A wealthy man, he helps most of the other characters, motivated by a combination of goodness and guilt at the mischief and human misery caused by Jarndyce and Jarndyce, which he calls "the family curse."

Mrs Jellyby is Caddy's mother, a "telescopic philanthropist" obsessed with an obscure African tribe but having little regard for the notion of charity beginning at home. It's thought Dickens wrote this character as a criticism of female activists.

Caddy is Esther's friend, and a secretary to her mother.
