The Charm School by Nelson DeMille

Painfully slow and long but a very interesting story. It was hard to get through the first half of the book and hard to put it down the last half. The author obviously knows the subject matter. On the road from Smolensk to Moscow, an American tourist, Gregory Fisher, is confronted by a man on the run: an Air Force major who was shot down over appears from his hotel and soon turns up dead, the victim of a suspicious car crash. Intelligence officer Sam Hollis, press attache Lisa Rhodes and CIA bureau chief Seth Alevy must discover for themselves what is going on at the Charm School. They must also decide whether public revelation of a horrifying KGB operation during the new era of glasnost might not damage American/Soviet relations.
