In the Enemy’s House: The Secret Saga of the FBI Agent and the Code Breaker Who Caught the Russian Spies

In this gripping exploration of Cold War spycraft, Blum (The Last Goodnight) lays out the complex chain of circumstances that led to the exposure of a major Soviet spy ring responsible for stealing America’s atomic secrets during and after WWII, and culminated with the execution of Julius and Ethel Rosenberg. As Blum follows the exploits of FBI agent Bob Lamphere and genius code breaker Meredith Gardner, he lays out the difficulties they faced in patiently unraveling the espionage network, one suspect at a time. To follow the trail to its source, they decrypted each stage of the code, compared it to a treasure trove of uncoded Soviet cables, and had to “re-create the KGB codebook” in order to match code names to actual people (“Kalibre” was Ethel Rosenberg’s brother, David Greenglass). Through extensive research and interviews, Blum brings a widespread cast of significant participants to life, from Lamphere and Gardner (from their awkward first meeting: “Meredith once again appeared to give the question considerable thought. But whether that was really the case... Bob could only guess. He found the man across from him inscrutable”) and their Soviet counterparts to the Rosenbergs and their many colleagues. Concise yet packed with details, this is a true page-turner, sure to appeal to those interested in the history of espionage or the Cold War. Photos. [em](Feb.) [/em]
