Secrets of the Darkest Art

Every fictional library needs a book that has been taken off the shelves, and this is the wizarding world’s. What makes it more interesting than the usual forbidden tome is that the censor is the hero.

Dumbledore does not merely restrict it. He removes it from the Restricted Section — a section that already exists specifically to hold books like this — and takes it into his own office, which is the act of a man who has concluded that his own institution’s safeguards are insufficient. He had watched a sixteen-year-old walk into that library, find this book, and walk out with enough information to derange the next fifty years. The removal is a confession of failure.

It also sets up the series’ most interesting argument, which the books never quite settle. Hermione steals it and is right to: the information that finally lets them finish the job is in there, and nowhere else. Suppressing the book did not stop Riddle, and it very nearly stopped the people trying to undo him. Dumbledore’s censorship costs the good side more than the bad side, and this being a children’s series, nobody says so out loud.

On the readability rating. We learn what it contains and what it enabled, and Hermione reports its conclusions. The text itself stays closed on the page — a book about soul-splitting that the author, sensibly, declines to publish.
