After seeing this, I went over to Gutenberg to find and read Head of the House of Coombe and Robin. I've been reading Testament of Youth and thought they'd be interesting complements.

Finished Head and I can't decide whether Robin is a manic pixie dream girl whose purity is going to save someone, or if worse is in store for her. The books are so very sentimental that the character is difficult to take at face value.

This kind of older-man-protects-younger-girl can go so very off the rails for modern readers (e.g. Daddy Long-Legs) but Burnett seems to be keeping it under control so far. (Indeed this trope seems to be one of her Things.) Nonetheless, this pair of books clearly wants to be adapted into a manga or anime series.
