Is There a Puzzling on the Page in a Book?

A wonder if there's been books that you've read that really where you were immersed in a kind of detective story, or someone's attempts to get emotionally to the bottom of something. Have there been any sort of examples of memoir or non fiction by writers that you've reading and gone or lias? I think for a certain type of writer, i think puzzling on the page is almost like the best thing they do," she says.
