           Miss Murdstone is a severe and inflexible woman, cold and hard like the rocks, and very sharp and suspicious too; she glory in the suspiciousness when she examines the whole house in unusual hours in order to find some man hidden for the servants. When her dear brother says something she have the habit of corroborate it repeating whatever he says, doing a ridicul efect of echo. She loves to seem offended and that everyone tell her how indispensable she is, and it is for this that she is saying always her presence is superfluous...

          When Mr and Miss Murdstone visit the house of Miss Trotwood and they are so badly received for her (when they arrived riding a pair of donkeys), Miss Murdstone and Miss Trotwood have an amusing quarrel in wich the one gets the worst part. Since this momentthe reader don't expect her return to the narration, but times later, when david meets the lovely Dora (daughter of one of his bosses) she appears again as the "confidence-woman" of this one, who left her mother when she was little.

          When David and Dora begin their candid relation Miss Murdstoneis nearly to destroy this one, when she find a letter of David inthe mouth of Jipp (Dora's little dog). Finally she disappears forever when Dora's father dies in a disafortunate accident and she goes to live with her old aunts.
