I am a great fan of the writing of Richard Brautigan, so I was delighted once to encounter a short reminiscence of Brautigan by that Zelig of the Beats, Pierre Delattre, in his fascinating memoir, Episodes (page 54):

The last time I saw him [RB], we were walking past the middle room of his house. There was a table in there with a typewriter on it.   “Quiet,” he whispered, pushing me ahead of him into the kitchen. “My new novel’s in there. I kind of stroll in occasionally, write a quick few paragraphs, and get out before the novel knows what I’m doing.  If novels ever find out you’re writing them, you’re done for.”
