The Serpent Under by Bonnie MacBird
I guess we need to look at The Serpent Under in a few different ways. First, Victorian London. MacBird does a fabulous job of bringing the foggy, damp, crowded city to life. We see the people, issues, and prejudices of the time.
Second, our main characters. Holmes and Watson feel like the originals, if that makes sense. They have the mannerisms and partnership they always have. Yes, Holmes' attitudes towards women, Roma, etc. are more modern, but he was never conventional. And here it particularly works well since it doesn't allow him to just go along with the easy solution. We only get brief glances of Lestrade and Mycroft, which is appropriate. Heffie, a former irregular who now works with the police, is a good addition. She's tough and reliable and very good at working undercover. The dead woman's family and friends are all a bit odd and she seems to have been the only truly likeable one of the bunch.
