C.O.W.L. is a comic book that combines crimefighting with the politics of organized labor. The comic borrows characters, setting, and ideas from Kyle Higgins’ earlier comic The League. There are elements of film noir at work here, both in the shadowy art style, and the mystery that is unfolding in the comic. The book certainly has all the elements of a solid mystery: set in a city known for powerful players and corrupt politics, a dead man with dangerous information, and people with reasons to be paranoid.
