CIA agents are being killed off by a critter which died out sixty-five million years ago, as well as an acronym (IWIW) which summons the critter, making it all the more mysterious. Also a dark tower which seems to have died out ten thousand years ago re-appears in Nevada, marked by a string of Fs in CIA speech. As in ''The fuuuuuu?'' It's OK if you're a big author you can do what you want.
