ActuaBD.com: Classiques Illustre
The news site ActuaBD.com has a news brief about Casterman exploring adaptations of current literary works into comics form. This includes the Tardi version of Pierre Siniac's Monsieur Cauchemar called L'Etrangleur that was serialized in newspaper form and that Bart Beaty talked about here. Other than that, what you might notice is that the effort is kind of all over the place in sort-of appealing fashion: some authors working on adaptations, material drawn from a lot of different sources, and so on.
