Astonishing ... An amazing and gripping tale, full of suspenseful twists and cinematic details — though it must be said that Otto Kuehn’s espionage efforts were characterized by a fundamental sloppiness that might have been almost comical, had the consequences not been so dire.
Kuehn’s carefully constructed narrative features some wonderful writing that helps the story glide from Europe across the globe and back again. A well-developed cast of characters and a strong sense of place make for a gripping story, despite the limitations of Kuehn’s conceptual framework.
A fascinating espionage story ... Ms. Kuehn, who has worked in journalism and public relations, is a vivid writer and movingly conveys the 'open-mouthed' shock that came with these revelations. Some elements of the account remain frustratingly unclear ... These flaws don’t loom large: The story is too compelling.
