I just coincidentally spotted this in a recs list:https://archiveofourown.org/collections/yuletide2017/works/13097577 I don't know the Baby-Sitters Club at all though. I do sense overall that there's been a move from small book fandoms, and less of the stuff based on folklore, myth and medieval lit. that I've often enjoyed. There's a nice Canterbury Tales casefic with the Wife of Bath as sleuth.
