Meh. Not awful but far duller than it should have been. Despite the presence of a crazed serial killer directly menacing our characters there is a curious lack of conflict here. The plot is too straightforward, lacking the twists and turns the reader expects in a mystery, and the world building (historical and fantastical) is way too thin. This doesn't read like historical fiction at all. None of the characters seem like people from 1915. And the ghost element is totally half baked. There's just not a lot to this story.
