Spy vs. Guy fiction
This page is the core of the fiction - "literary espionage," "the literary thriller," or maybe spy novels rather than spy novels. No one really seems to know what to call it, but it's completely distinctive. I call it Spy Vs. Guy, because that seems to be the main conflict: instead of the story being about which side spies better than the other (or averts some catastrophe), it's about the war between "spying" and "me" inside a character's head.
The distinction between these stories and Thrillers is independently described in two other works: The Silent Game: The Real World of Imaginary Spies and The Man Who Kept the Secrets. See as well Spy Fiction: A Connoisseur's Guide.
I'm serious about the kids' books being in there, too. The hero of Harriet the Spy almost becomes the anti-hero of A Perfect Spy, and fortunately does not succeed. The Stasi presence in Freya on the Wall is serious business.

 Kids' books
Kind of a grab-bag category including novelists who published one book and then vanished, young authors with only one or two books so far, limited excursions into spy fiction by more general authors, politicians, spies, or journalists who felt an overwhelming need to write fiction too, for a bit. A couple are two- or three-shots, of course.
