Mr. Brocklehurst, I believe I intimated in the letter which I wrote to you three weeks ago, that this little girl has not quite the character and disposition I could wish: should you admit her into Lowood school, I should be glad if the superintendent and teachers were requested to keep a strict eye on her, and above all, to guard against her worst fault, a tendency toward deceit. I mention this in your hearing, Jane, that you may no attempt to impose on Mr. Brocklehurst.

Jane Eyre, Chapter 4. When Mr. Brocklehurst, supervisor of Lowood charity school for poor girls, arrives at Gateshead to decide if Jane will be accepted at his school, Mrs. Reed warns him that her niece is a liar. Her accusation about Jane is ironic, as Mrs. Reed is actually the deceitful one.
