JSA Liberty Files: The Whistling Skull

Set during World War II in DC’s alternate-history “Liberty Files” universe, this six-issue miniseries from 2013 follows a covert team of American operatives—including a mysterious, skull-masked agent—as they battle a supernatural threat from Nazi Germany. Writer B. Clay Moore and artist Tony Harris craft a gritty, period espionage tale that expands the shadowy corners of DC’s wartime mythology. It matters as a standalone, creator-driven exploration of the era’s pulpy, paranoid atmosphere, distinct from mainstream superhero fare.
