In June 1973, Jerry Pournelle sent him (Heinlein) a gigantic manuscript for a science-fiction novel he had written in collaboration with Larry Niven, Motelight (what would become The Mote in God’s Eye), and Heinlein girded up his mental loins for another job of analysis and technical critique. As he read, though, he found himself turning pages, getting involved with the characters and the story. But it had a major fault as a book that urgently needed to be addressed. He spent three days going through the manuscript almost line by line, and finally, on June 20, sat down at the typewriter to frame his critique. His first note to the authors was:
“This is a very important novel, possibly the best contact-with-aliens story ever written.… (best aliens I’ve ever encountered, truly alien but believable and one could empathize with them, every ecological niche filled, total ecology convincing, etc.—grand[.])”
With Pournelle, he knew he could be straightforward and even blunt—and there simply was no “delicate” way of saying some of the things he thought needed to be said—
"We are in a highly competitive market, battling each year against not only thousands of other new novels but also TV and a myriad other things […] in the late XXth century one simply cannot use up 30,000 words before getting down to business with the main story line[…]
"How to correct the major fault? I don’t know. It’s your story. But cutting the bejasus out of those [first] 100 pp would help. It is all featherdusting, not story, and you need to determine just what supporting data must be saved to keep the plot intact—then see how much of it can be tucked away into corners after page 100, and what is left that must be on stage before page 100—and what is left be told in such a way as to grab the reader and pull him along, not lose him."
Heinlein’s experience with this kind of hard-love advice was not encouraging: “People seldom take advice—and this advice you did not ask me to give. I shan’t be offended if you don’t take it; I hope that you will not be offended that I proffer it.” He sent off the long letter to Niven and Pournelle[…]
In early August, Larry Niven and Jerry Pournelle surprised him with a revision of Motelight. He was shocked to see that they had taken his criticisms not merely in the spirit in which they were given, but as blueprints, even withdrawing the book while they reworked it:
"I am pleased (and much flattered) that you took my comments on the earlier version seriously. I cannot remember this ever happening in the past (and for this reason I long ago quit commenting on other writers MSS; it is almost always a waste of time—but I tried once more because I liked almost all of the earlier version so well). I know all too well how dear to a writer are his brain children; most writers usually will not accept criticism—and usually should not, as creativity is usually not helped thereby."
