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.
The villain is Crossfire, who will reappear a bunch of times with other names.
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.
Not canon.
