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

Oldham’s suicide did little if anything to alert the Foreign Office to the chronic problems of its own security and that of British embassies abroad.⁴⁴ Still concerned by fears that he was being pursued by a secret British assassination squad, however, Bystroletov failed to grasp how relatively unprotected a target the Foreign Office remained. He concluded that a safer recruiting ground was Geneva, where several of Oldham’s former colleagues were working as cipher clerks with the British delegation to the League of Nations. In December 1933 he made contact there with Raymond Oake (codenamed SHELLEY), one of the most promising potential recruits in the communications department identified by Oldham.⁴⁵ Oake had good reason to resent his underprivileged status. Since joining the Foreign Office in 1920 he had remained in the lowly rank of “temporary clerk” without pension rights.⁴⁶ Bystroletov handed over the cultivation of Oake to the Dutch artist Henri Christian (“Han”) Pieck, who operated as an OGPU illegal codenamed COOPER.⁴⁷

Pieck was almost as flamboyant an extrovert as Bystroletov, with a convivial manner which won him a wide circle of friends and acquaintances among British officials and journalists in Geneva. He invited Oake and other cipher clerks to stay at his house in The Hague where he lavished charm and hospitality on them while assessing them as possible recruits. Oake’s main service to Soviet intelligence was to provide an introduction to Captain John H. King, who joined the Foreign Office communications department as a “temporary clerk” in 1934⁴⁸ and subsequently became a far more important agent than Oake himself. Pieck reported that King had been born in Ireland, considered himself Irish rather than British and, though anti-Soviet, also “hated the English.” Estranged from his wife and with an American mistress to support, he found it difficult to live on his modest Foreign Office salary. Pieck cultivated King with patience and skill. On one occasion he and his wife took King and his lover for an expensive touring holiday in Spain, staying at the best hotels. Mrs. Pieck complained that the whole holiday had been “a real ordeal” and that King and his mistress were “incredibly boring.”⁴⁹ The Piecks’ hospitality, however, paid off handsomely. Seven months after his first meeting with Pieck, King (henceforth codenamed MAG) began to hand over large amounts of classified material, including Foreign Office telegrams, ciphers and secret daily and weekly summaries of diplomatic correspondence.⁵⁰

AN ANALYSIS BY the Centre concluded that about 30 percent of King’s material was the same as that provided by Francesco Constantini (DUNCAN), the long-serving OGPU agent in the British embassy at Rome.⁵¹ The overlap was, almost certainly, regarded as useful for checking the authenticity of the documents received from both agents. It was a sign of the importance attached to Constantini’s intelligence that Abram Aronovich Slutsky, who succeeded Artuzov as head of INO in 1934, decided to transfer him from the legal residency in Rome to another of the Great Illegals, Moisei Markovich Akselrod (codenamed OST or OSTO), one of the leading Soviet agent controllers. Born into a Jewish family in Smolensk in 1898, Akselrod had been a member of the Russian branch of the Zionist socialist organization Poale Zion, until its dissolution in 1922. He then joined the Bolsheviks and in 1925 began a career in INO.⁵² Like most of the Great Illegals, Akselrod was a remarkable linguist—fluent in Arabic, English, French, German and Italian—and, according to a fellow illegal, a man of “extraordinary culture” with “a fine indifference to risk.”⁵³ In 1934 he traveled to Rome on an Austrian passport to establish a new illegal residency and act as Constantini’s controller. He had his first meeting with Constantini in January 1935.⁵⁴
