11.  The Ransom of Russian Art, John McPhee, 1994.  The commenter who recommended this book wrote this, “Whether it’s due to common interests, shared membership in an old boys’ network, or whatever, high-level academics doing stuff for the CIA has been a thing for a very long time. For a case study that is also a very fun read, see the later chapters of John McPhee’s “The Ransom of Russian Art” (1994).
