Riffs on the fact that a lot of classic monster stories involve the creation, and subsequent destruction / abandonment, of a monstrous woman. After the death of her parents, Mary Jekyll digs into her late father’s affairs and discovers not just a previously unknown sister named Diana Hyde, but other women who were brought into being by famous fictional mad scientists. The women band together to make their way in the world, helping Sherlock Holmes and Watson solve a string of murders along the way. The writing was perfectly decent, but the plot felt really more like a way to string together all these related stories, and there were so many characters that none of them felt particularly fully-realized.
