Answer:
To create suspense, writers must reveal details gradually so readers want more.
Explanation:
Lee Child's "A Simple Way to Create Suspense" is an essay where he narrates or rather expressed his take on creating suspense in his works. The essay provides his approach to making a suspenseful work rather than directly approaching the climax in a story.
In the given paragraph from the end of his essay, he states that there are numerous ways to make work interesting. He agrees that "Attractive and sympathetic characters re nice to have; and elaborate and sinister entanglements are satisfying .... [added with] impossible-to-escape pits of despair". But all these are "luxuries" which provide not enough thrill. Rather, he opines that "the slow unveiling of the final answer" is the basic narrative fuel of any work.
Thus, the central idea of the passage is that writers must reveal details slowly and gradually so that the readers will want more, creating a suspenseful environment.
