Ok, I couldn't wait. It was Albemuth. Googled it and found this:

"I returned to the typewriter and drafted another statement. It was
important to do a good job.

TO THE AUTHORITIES:

I, Philip K. Dick, have never liked you, and I know from the burglary
on my house and the fact that you are busily at work hiding dope in
the light sockets and telephone as I sit here that you don't care for
me either. However, as much as I dislike you, and you me, there is
someone whom I dislike even more, to wit: Mr Nicholas Brady. I suggest
that you dislike him too. Let me outline why....."
