Another popular one could be 'A Red Herring Without Mustard'. It builds on the world established in the first book. There are more complex mysteries and Flavia's relationships with the other characters in the village start to develop in more interesting ways.

Well, it's a bit of a mix. While it may be inspired by some true elements from 1899 such as the general state of the world, sea travel, and social hierarchies at that time, it also has a lot of fictional elements added for the sake of drama and mystery.
