This book is apparently a sequel, I only found that out after having listened to it and I can assure you that it is entirely self contained and you do not have to read/listened to the prequel. As the blurb suggests we have an investigation within the story, the lead character is trying to find the cause of various strange events. We follow the lead characters through his failures and successes. This story by Jules Verne is not so much an adventure as a slow paced investigation into the unusual by a ploding investigator. There are one or two very brief moments of a speedier pace but thats all. All in all, it was a pleasant enough story but the plot was extremly thin. The reading is by Mark Smith, one of the excellent readers at Librivox.
