Marvel Two In One #52 was the second time someone other than Doug Moench wrote about Moon Knight and, just like the last time, it sucked. Author Steven Grant tried to create a background for the character that included being a CIA interrogator.
Fortunately, the very next year Marvel green lit the first volume of Moon Knight by Moench and Bill Sienkiewicz, and these other appearances were quickly forgotten.
Creators: Steven Grant and Jim Craig
