None was as mysterious as the woman known as Madam Zero. Little of her story is know of her since she only appeared in four issues of Fight Comics in the early 1950s.
Although these issues are available online, a solid collection of all her stories has been complied in Madam Zero Secret Files Collection. The introduction is fitting, making this collection well worth your time.
Below you will find Madame Zero's introduction from Fight Comics #82. Written by George Dennison (also the pen name on #83), art by "Charles Sultan" (who maybe Matt Baker, but I can't can't decide).
