This book is still somewhat difficult to peice together. Another of the 10 novels within one novel starts at this point, while either pausing or stopping the first story. The reader is also made a character in the novel, although your role is pre-scripted, much as it would be in a play. Unfortunately the acts do not seem to be coherent with one another. What about the story about the travellers on the train from the first story? What is the significance of including the Cimmerian and Cimbrian languages in this piece?
I know Natalya already covered this, but it did seem as though he was more interested in Ludmilla than his mystery novel too.
