^Hirako is a possibility too, most in the CCG whose loyalty isn't 100% and has a reason to help Kaneki is a suspect (watch it be Furuta because he's involved in damn well everything :'D). If it was Hirako, I reckon it would have been on Arima's behalf.

If the book was Hide's the signature is by Eto, if not then ??? Whether or not Hide was the one who sent it is a question, but I strongly feel that it was his copy. It's too on point not to be. There are a myriad of ways to have gotten Sasaki to learn his name, but the clue happened to be an autograph in the same novel that Hide had signed years ago as a gift. It's just...too many coincidences ya know?

Arima I think is obvious in retrospect. Now that we know more about him and his feelings towards Kaneki via the last few chapters he seems more likely as a candidate. At the time, or for a long time after, not so much. It's currently Kaneki's birthday though, so I feel that the sender might be revealed very soon.
