I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Poirot talking about Hastings: lots and lots of backhanded compliments.
"Always, when I have had a big case, he has been by my side. And he has helped me - oh yes, often he has helped me. For he had a knack, that one, of stumbling over the truth unawares - without noticing it himself, bien entendu. At times, he has said something particularly foolish, and behold that foolish remark has revealed the truth to me!"
