Anne Applebaum’s Pulitzer Prize-winning Gulag was part of that process and now she has written a complementary volume: Iron Curtain is a superb, revisionistic, brilliantly perceptive, often witty, totally gripping history, filled with colourful character sketches of Stalinist monsters, based on Soviet and local archives, on hundreds of interviews with survivors, and on the widest reading, that tells the dramatic, unknown and terrifying story of the Stalinisation of eastern Europe. She concentrates on Poland (where her husband Radek Sikorski is foreign minister), Hungary and East Germany. The book is full of things I didn’t know — but should have.
