One of my favorites is the portrayal of N.I.C.E. director John Wither in "That Hideous Strength" by C. S. Lewis. (especially Chapter 3, "Belbury and St. Anne’s-on-the-Hill")
(didn't want to give too much away, but when you've read the story and understand N.I.C.E. a bit more, you'll see how incredibly creepy Wither's nonchalance is. Should be a primer for working anywhere known for a culture of fear.)
