Jane Murdstone is Mr. Murdstone's sister; she comes to live at the Rookery following her brother's marriage to Clara Copperfield, ostensibly to relieve Clara of some of the housework. Miss Murdstone resembles her brother closely in both looks and personality and takes just as much (if not more) pleasure as he does in controlling Clara and terrorizing David. It is not clear whether this obsessive devotion to Mr. Murdstone's plans reflects genuine love for her brother or simply a desire to exercise her own authority. Regardless, in Miss Murdstone's unofficial position as housekeeper, she quickly overhauls the household according to strict ideas about efficiency and organization (this is also a power play, since it makes Clara and David feel like guests in their own home). Later in the novel, Miss Murdstone resurfaces as an impediment to David and Dora Spenlow's love affair, which she attempts to thwart by informing Dora's father, Mr. Spenlow, of the couple's intention to marry. Miss Murdstone's involvement in this episode underscores the similarities between Dora and Clara.
