This is the second part of the only original X-9 comic book story produced in the U.S. up to this time, a five-part story appearing in issues #4–8 (1967). The first part ("The Key to Power") was written by Archie Goodwin and drawn by Al Williamson. The other four parts remain officially uncredited. The art has been erroneously attributed to Reed Crandall and Dan Spiegle. Mark Evanier has expressed the opinion that the artist is either Mike Roy or Frank Springer, who is tentatively credited by this indexer.
