There appears to be a gap in the story between the file named and the next one in the Basara section. Because the 'a' part only seems to get added for chapter split over sever seveal files I assume that there also exists a 'b'-part and perhaps even a 'c' or 'd'. I guess that instead of not existing at all it simply got lost among the confusing file names.

It would be very nice if it could be added.
