What is the book that is a line by line refutation of Keynes' theory?

I remember seeing a post a month or two ago that referenced a specific book and I am trying to recall the title.

I believe it was described on this forum as “a line by line refutation of keynes’ economic theory”

If anyone knows what I’m referring to, it would be great to have the title of the book.
