I'm not sure if Patterson was simply being completely insensitive - or whether he was trying for an unsubtle rewrite of Misery:

James Patterson scraps The Murder of Stephen King novel - BBC News
Author James Patterson has scrapped the publication of a new novel titled The Murder of Stephen King because he does not want to cause “discomfort” to King.
The book is about a fictional obsessed fan hunting down King, the author of Misery, The Shining and Carrie.
But Patterson said he had learned in the run-up to the planned November publication that fans had “disrupted” King’s home in real life.
King has had nothing to do with the novel, Patterson has stressed.
. . . .
However, in a statement released by his publisher on Thursday, Patterson – who co-wrote the book with Derek Nikitas – said: “My book is a positive portrayal of a fictional character, and, spoiler alert, the main character is not actually murdered.
“Nevertheless, I do not want to cause Stephen King or his family any discomfort. Out of respect for them, I have decided not to publish The Murder of Stephen King.”
