This is an old trick of posioning

I read it in bengali detective story in the childhood as I used to read only and only detective and crime stories. This is an old trick. The pages of the manuscript has poison in the corner. So if you know someone has bad habit of licking the fingers and turn the pages, you can put poison in the corner and slowly kill that person. So, KK must be the culprit as KK gave the book to Pravakar.

I can your theory is coming form Pheluda's and Byomkesh's wisdom :)

Not Humayun, he fell down the stairs and died

he fell off stairs after reading books, whose pages were poisoned. This was what was told in my history class. Humayuj had a huge Library and was a voracious reader, and it was a conspiracy by someone in his own kingdom to kill him
