In fiction, when you paint yourself into a corner, you can write a pair of suction cups onto the bottoms of your shoes and walk up the wall and out the skylight and see the sun breaking through the clouds. In nonfiction, you don’t have that luxury.
Tom Robbins
Of course, after you’ve written the suction cup escape, you then have to go back and rewrite however much of your story needs to be rewritten in order to make such an escape believable within the context of your novel.
In nonfiction, you have the much greater luxury of not having to make things up. Consequently, you never get painted into a corner. There is always an exit marked ‘THIS ACTUALLY HAPPENED NEXT’.
Only if it’s ‘in character’.
