After the collapse of the Soviet Union, historian Allen Weinstein was offered an unprecedented, and, as it would turn out, singular, chance to rummage through the KGB archives. Out of those archives, he brought this book, which describes the Soviet Union's extensive spying campaign in the United States during the presidency of Franklin Roosevelt. It's understandable that Weinstein wanted to get as much of this information into print as possible, so parts of this book can read more like a reference, with lists of purloined documents and of dates of meetings. But, at its best, the book offers a near-transparent window into the world of espionage, with tales of good and bad tradecraft (konspiratsia, as the Russians called it), of code names and encrypted telegrams, of moles and honeypots, and all the rest.
One constant in the book is the Soviet operatives' frustrations with their American agents' (known as "probationers," later "masters) amateurish ways. Since many of them were recruited through the above-ground Communist Party USA, and by Party chair Earl Browder, many of them continued to know and work with each other in the "underground." Many of the group preferred to think that they were just getting information for the CPUSA, or the Comintern, not the KGB, but sooner or later most wised up. The Victor Perlo Group of spies, most who worked in mid-level Washington positions, and who made contact with the KGB through the American courier Elizabeth Bentley, would meet regularly at each others' apartments, bringing notes about their findings and having their wives type them together. This violated basic norms of compartmentalization and exposed the whole group to danger. Soviet Operative Joseph Katz reported back to Moscow that "Taking into account the state of konspiratsia, one cannot do much," but he tried to persuade them to work individually as much as possible. Another problem was that Perlo, like many Soviet spies, had personal problems. Perlo was in such a spat with his ex-wife that she sent a letter to President Roosevelt identifying most of the group by name. Yet the Roosevelt administration ignored the letter, as it did many other indications of espionage, until Elizabeth Bentley's defection in November 1945 exposed proved many of the letters' claims to be accurate. Bentley's defection also led to the end of major Soviet espionage in America. Just as the Soviets operatives had warned, the amateurish and collegial American network, which worked more like a "cell" than a series of spies, was liable to crack after just one failure.
Elizabeth Bentley herself is one of the most fascinating characters in the book. Like many others, she provided the KGB with a revealing self-portrait. She said in college "I was shy and a virgin," but then described four affairs before she met the Communist agent Jacob Golos. When a Communist friend tried to convince her to sleep with other people for information, however, she refused, after which the friend called her a Trotskyist and threatened to kill her. Still, many of her Soviet handlers were suspicious of her connection with Golos, who insisted on running his own cohort of agents without direct intervention of the KGB, and who increasingly complained about the Soviets' desire for direct control. Golos's untimely death in 1943 increased their suspicions about Bentley's independence. New York Station Chief Itzhak Akhmerov wrote that Bentley continued sleep with women, even while she complained about her 'lack fo a male friend to satisfy her natural needs." Akhmerov wrote Moscow that "I would like to resolve Bentley's person problem. As I wrote you she is a rather attractive person." He proposed sending a Polish or Baltic refugee. "We'll arrange the rest... It will bring great happiness to our operative." After she defected, however, the station pivoted, and discussed numerous ways of killing her (car crash, fake suicide, shooting), but didn't get approval from Moscow until it was too late.
There's lots of stuff about the atomic spy ring (everyone from Julius Rosenberg to David Greenglass to Klaus Fuchs) and the group run by Whittaker Chambers, including Alger Hiss and Harry Dexter White (although less on this front, because that group was run by the GRU, Soviet military intelligence, or "the neighbors" as the KGB called them). The book is too detailed and tedious, but you'll likely never get a comparable look at spycraft, during its peak, and during its most essential moment.
