So, I was searching Internet for som theories about Hide and where he disappeared after Tokyo Ghoul, and this seems to be quite accurate.

There was also this theory about who sent the book to Kaneki, and based on the research author made Hideyoshi is our mysterious sender (or at least it's his book).
