'This is an engagingly written and extremely topical book that sheds new light on the important relationship between political transition and the reform of security services. The authors explore the concept of security intelligence and place the discussion of post-Communist Europe within the wider context of transitions from authoritarian rule and security-sector reform. The substantive chapters on Czech, Slovak and Romanian security services are extremely well researched and shed new light on the intricate details of security reform; one cannot find this detailed information elsewhere in English-language sources. This is an important and informative book.' - Charles King, Ion Ratui Chair of Romanian Studies, Georgetown University
