The fics that time forgot.

After ten years, it is worth looking back to find fics that I forgot to finish. The ones most interesting to me right now are
Indifferent - A Sherlock/Moriarty backstory fic
https://archiveofourown.org/works/5211005

and Among the Ruins - A Harry Potter / Draco with both of them as married fathers.
https://archiveofourown.org/works/19319872/chapters/45955216

My finished fic to read, because I have forgotten most of the plot now is
In Service of the State - a 10,000 word Anthea(not Anthea)fic that tells how she started working for Mycroft.
