This is a really excellent piece of work. Amy Knight has produced what is billed as the first biography of Beria and one it will be hard for any future writer to outdo. The book is determinedly unsensational, meticulously researched and annotated, and well-written. We are given a rounded picture of a brutal opportunist who could be pragmatic when the occasion called for it. The book speculates interestingly and plausibly on what might have happened had Beria succeeded in his bid to succeed Stalin. Khrushchev, who got the job in the end, adopted many of Beria's policies. My only minor gripe is that the switch from looking at Beria's myriad bad points to his good ones jars sometimes. But if you want to know more about a key, but shadowy, figure from the Stalin era, read this book. They don't come much better.
