I Killed Adolf Hitler, by Jason (Fantagraphics Books, 2006)

A hitman is hired to travel back to 1938 via time machine to kill Hitler. Deadpan SF black comedy in the author/illustrator’s signature style, which deftly explores the potential for complications in the premise. There’s depth in the approach; appreciating the deceptiveness of the apparent simplicity of Jason’s work is part of the pleasure.

My own books are here, if that’s your thing. Newest is noir thriller East of England.
