Last week Dark Horse reintroduced English-reading audiences to Juan Díaz Canales and Juanjo Guarnido's "Blacksad," with a new hardcover collecting the first three volumes of the planned four-part series. We weren't shy in our excitement for the new release, especially as it localized the series' third volume for the first time, and other blogs responded with similar praise. It wasn't until Boing Boing's most recent online advocacy for the title hit that we got a look at what could very well be artwork from the last volume of the series, "L'Enfer, Le silence," which is rumored to be slated for release in France this fall.

Commenter GNP linked out to an unconfirmed cover for the title, as well as a possible interior page and a single panel. We're still looking into their authenticity, but they certainly seem plausible based on aesthetics and the Dargaud logo stamped on the seemingly official French cover.
