For Fang Zheng and Conan, many doubts surrounding the Rokkenjima incident still remained unresolved.
The first doubt was whether Beatrice had truly existed.
The clues so far suggested... that such a person very likely did exist.
There really was an annex on Rokkenjima, but Conan had said that it looked as though no one had lived there for over a decade.
Thinking about it the other way around, that meant someone had lived in that annex ten years ago.

"Bernkastel doesn't know Kanon's
