The Sword and the Shield: The Mitrokhin Archive and the Secret History of the KGB

This failure… resulted in the decision whether or not to prosecute Mrs. Norwood effectively being taken by the Security Service. The Committee is concerned that the Service used public interest reasons to justify taking no further action against Mrs. Norwood, when this was for the Law Officers to decide. We also believe that the failure of the Security Service to interview Mrs. Norwood at this time prevented her possible prosecution.

For the next five years, owing to “a further serious failure by the Security Service,” the Norwood case “slipped out of sight.”[16] MI5 may not deserve a great deal of sympathy for its oversight, but it does deserve some. The first priority of any security service are actual, followed by potential, threats. Among the mass of material provided by Mitrokhin in 1992, the case of the eighty-year-old Mrs. Norwood, who had last been in contact with the KGB over a decade earlier and no longer posed any conceivable danger to national security, must have seemed a very low priority — particularly given the strain on MI5’s resources caused by cutbacks at the end of the Cold War and the threat from Irish terrorist groups.

Arguably, however, MI5 underestimated Mrs. Norwood’s past importance. In evidence to the ISC, the Security Service concluded that her “value as an atom spy to the scientists who constructed the Soviet bomb must have been, at most, marginal.”[17] That was not the view of the NKGB (as the KGB was then known) in the final months of the Second World War. In March 1945 it described the atomic intelligence she had provided as “of great interest and a valuable contribution to the development of work in this field.”[18] Though Mrs. Norwood was not, of course, an atom spy in the same class as Ted Hall and Klaus Fuchs, both of whom provided intelligence from inside the main nuclear laboratory at Los Alamos, the NKGB and the Soviet scientists with whom it was in close touch plainly regarded her intelligence as somewhat better than “marginal.” The intelligence she was able to provide on uranium fuel cladding and post-irradiation corrosion resistance was probably applicable to weapons development as well as to the construction of nuclear reactors.[19] Until the final months of the War, the NKGB rated the atomic intelligence obtained in Britain almost as highly as that from the United States.[20]

As Jack Straw told the Commons when announcing the ISC inquiry, “There is no reason to doubt… that the KGB regarded Mrs. Norwood as an important spy.” Nor is there reason to doubt that she was both the KGB’s longest-serving British agent and its most important female British spy. From early in her career, the KGB had high expectations of her. It maintained contact with her in 1938-39 at a time when the shortage of foreign intelligence officers, many of whom were executed during the Terror, led it to lose touch with many other agents — including some of the Magnificent Five. Since the publication of The Mitrokhin Archive, Viktor Oshchenko, a former senior officer in the KGB scientific and technological intelligence (S) directorate, has kindly given me his recollections of the Norwood case. While stationed at the London residency in 1975, Oshchenko recruited Michael Smith, the KGB’s most important British S agent during the later Cold War.[21] He remembers Mrs. Norwood’s career as a Soviet agent as “a legendary case in the annals of the KGB — an important, determined and very valuable agent,” and was deeply impressed both by her ideological commitment and by her remarkable access to her boss’s papers. Among the intelligence which Oshchenko believes Mrs. Norwood supplied were “valuable papers relating to the materials involved in missile production.”[22] Details of the use made of Mrs. Norwood’s intelligence within the Soviet Union, however, remain scarce. Mitrokhin’s notes from her file, though giving precise information on Mrs. Norwood’s controllers and other operational matters, give little indication of the doubtless complex intelligence she supplied in the course of her long career as a Soviet agent. It is highly unlikely that the SVR will reveal any details of this intelligence until after Mrs. Norwood’s death.
