Detective Conan: Two-Faced

Any Stories Where Kudo Shinichi Toys With the Red Faction While Working for the Black Faction, Without Turning Good, and With a World-Weary, Purely Black Protagonist?

Looking for books similar to "Ye Luoli: The Rise and Fall of the Water Kingdom". I want an angsty Shui and Shi story, really heartbreaking and not sweet at all.

Stories About Shinichi Kudo, Preferably One Where He Joins the Black Organization

I'm looking for books like "The Great Detective in the Distillery". I'd especially like one where Shinichi Kudo or Conan isn't on the side of justice, but instead helps the dark side.
