I read this one years ago. Clark was helped out by a mysterious madam located in Metropolis who helped her employees move on to a better life after working for her.
Arianna Carlin-Luthor was also in the fic, in the end she was fatally wounded.
A writer's job is to think of new plots and create characters who stay with you long after the final page has been read. If that mission is accomplished than we have done what we set out to do, which is to entertain and hopefully educate.
