The more Klein thought about it, the more likely it seemed. Otherwise, who would have borrowed those random journal issues for no reason?
Yes, research regarding the main peak of the Hornacis mountain range is quite an unpopular field. Other than the corresponding lecturers and associate professors, the common hobbyist would've never heard of it. Even the original Klein, who was a history graduate, only knew about it from the Antigonus family's notebook… Although Tingen is a city of universities, there wouldn't be that many people who would interested in the topic. And even if there is anyone interested, most of them would remain within the university's compounds. There would be no need to borrow the book from the Deweyville Library.
The most important point is that the book happened to be borrowed only recently…
