I want to know the answer to the following question:
What three titles were part of the darker, grimmer Marvel Knights comics?
All the background I'm provided with is that "In 1998, the company launched the imprint Marvel Knights, taking place within Marvel continuity; helmed by soon-to-become editor-in-chief Joe Quesada, it featured tough, gritty stories showcasing such characters as the Inhumans, Black Panther and Daredevil.". Is that enough to answer the question?
