The fic has an unauthorized sequel called " Heaven & Hell by Palinurus. ("Part 1 of the 'Grey Zone' series. An unauthorized sequel to Brenda Antrim's 'Paybacks'. The agent, encouraged by his boss, explores new possibilities.")
Printed in an Unknown Zine
At some point (likely the early to mid 2000s) this story was printed in an unknown zine, along with Authority, and other fic. It is unknown if this was with or without permission.
Slight Title Variation
A fan in 1997 refers to the title as "Paybacks," as does the zine version. The online version by the original author calls it "Payback."
