Jude was very curious about the Harry Potter novel so he went to a realiable source to learn the plot and conclusion. He simply could not wait for the book to come out.
The source spilled it and then said "I've told you; now I'm going to have to kill you."
So the source killed him.
This whole suicide thing is just a big cover-up. A conspiracy, I tell ya!
My typing sucks.
