PositiveThe Scotsman (UK)In An Impeccable Spy, Owen Matthews captures all the drama of Sorge’s story, and he has mined Russian and Japanese archives to provide his readers with what is now the standard work on Sorge. This is much more than a book for spy buffs, though. Jargon is avoided, the complexities of Soviet, German, Chinese and Japanese politics and infighting of the time are skilfully navigated and the personalities brought vividly to life. With this book as our evidence, we can say that Sorge was an impeccable spy, and also that Matthews is an impeccable biographer.
