Count Jagodic Family Mystery All of That Flatland

Since I have finished my book for my book project, I have started preparing for my Young Authors story, so i have started reading some books to get a bit of more of an idea for my book that I will be reading. I have stared reading a book called All of that Flatland,which is a book about a count Family Jagodic which is exposed to many mysteries about heir ancestors. The plot starts when one night a big fire occurs next to the counts mansion, the Counts wife dies in the fire, the Count and her had two sons which are after twenty years of waiting starting to resolve the mystery of who made the fire that night next to the mansion.
