"Jane Eyre remains the best of [Charlotte Bronte's] books [...] because while it is a human document written in blood, it is also one of the best blood-and-thunder detective stories in the world.

 In any case, it is Charlotte Brontë who enters Victorian literature. The shortest way  of stating her strong contribution is, I think, this: that she reached the highest romance through the lowest realism. She did not set out with Amadis of Gaul in a forest or with Mr. Pickwick in a comic club. She set out with herself, with her own dingy clothes, and accidental ugliness, and flat, coarse, provincial household; and forcibly fused all such muddy materials into a spirited fairy-tale. If the first chapters on the home and school had not proved how heavy and hateful sanity can be, there would really be less point in the insanity of Mr. Rochester's wife—or the not much milder insanity of Mrs. Rochester's husband. She discovered the secret of hiding the sensational in the commonplace: and Jane Eyre remains the best of her books (better even than Villette) because while it is a human document written in blood, it is also one of the best blood-and-thunder detective stories in the world.
