Many people have their best ideas come to them at night, in a dream, or as a result of some problem that just won’t let them sleep. For me, inevitably, a midnight wake-up is my subconscious reminding me that I’ve made an error. Like, say, writing a cliffhanger into a chapter and then realizing that the item involved wasn’t invented in the time period the chapter is set. This is a particular nuisance because I alway think I’ll remember to correct the error in the morning. Thank the Good Lord, this time I did. You won’t be seeing a miniscule camera in the Big Inch. Can’t promise other mistakes will be so easily identified.
