The day after Chambers met Berle, on 3 September, Victor Mallet, Counsellor at the Washington embassy, wrote to Gladwyn Jebb, who was then private secretary to Sir Alexander Cadogan (Vansittart’s successor as PUS at the Foreign Office). Mallet noted that Krivitsky had foretold the Russo-German pact: ‘he is clearly not bogus as many people tried to make out’. Mallet reported Levine’s information that Krivitsky knew of two Soviet agents working in Whitehall: one was King in the Office cipher-room, who ‘has for several years been passing on everything to Moscow for mercenary motives’; the other man was said to be in the ‘Political Committee Cabinet Office’. (Levine was to recall in 1956 that when he told the British Ambassador in Washington, Lord Lothian, about two Foreign Office spies, Lothian smiled in superior disbelief.) Mallet warned Jebb, ‘Levine is of course a Jew and his previous history does not predispose one in his favour, as he was [newspaper owner William Randolph] Hearst’s bear-leader to a ridiculous mission of Senators to Palestine in 1936 and a violent critic of our policy. But … he seems quite genuine in his desire to see us lick Hitler.’34
Cadogan asked Harker of MI5 and Vivian of SIS to investigate the Communications Department. Vivian, with SIS’s patriotic mistrust of foreigners, thought Krivitsky sounded ‘at the best a person of very doubtful genuineness’. King stymied his questioners during his first interrogation on 25 September, without convincing Vivian, who ended by telling him, in the rational bromide style of such interviews, ‘We had hoped that you might be able to clear up what looks like a very unfortunate affair, and if you can at this eleventh hour tell us anything, it will, I think, be to everybody’s advantage. I don’t think you will find us unreasonable, but it is depressing to find that you have been unable to tell us anything, except the specific things we have asked you about.’ They detained King overnight in ‘jug’, to use the slang word of Cadogan, who noted on 26 September: ‘I have no doubt he is guilty – curse him – but there is absolutely no proof.’35
Spurred by the emphasis on national security that had followed the declaration of war on 3 September, and independently of the information received in Whitehall from Krivitsky, Parlanti approached the authorities of his own volition and volunteered his strange story of the Herne Bay train and the Buckingham Gate lease. Hooper’s denunciation of Pieck was resuscitated from a moribund SIS file. Decisively ‘Tar’ Robertson got King drunk in the Bunch of Grapes pub at 80 Jermyn Street, rather as he had done six years earlier with Oldham at the Chequers pub a few yards away. Robertson got temporary possession of King’s key-ring, which enabled MI5 colleagues to visit King’s flat in Chelsea and find incriminating material. King was arrested next day. On 28 September, under what Cadogan called ‘Third Degree’ questioning in Wandsworth prison, he gave a full confession. MI5 witnesses at his secret trial in October were driven to the Old Bailey in cars with curtained windows to hide their identity. There were no press reports of the trial, which was kept secret for twenty years. King was sentenced to ten years’ imprisonment.36
Harker and Vivian suspected several of King’s colleagues, but had no evidence for prosecutions. The ‘awful revelations of leakage’ appalled Cadogan and his Foreign Secretary Lord Halifax: in December 1939 they swept all the existing staff out of the Communications Department, although most remained as King’s Messengers, and installed a clean new team. Dorothy Denny and other women were appointed to the department to dilute its masculinity, and thus to moderate its office culture, although the top departmental jobs remained in male hands.
Then on 26 January 1940 SIS informed Cadogan that there had been leakages from the FO’s Central Department to Germany during the preceding July and August. On 8 February Cadogan persuaded William Codrington (chairman of Nyasaland Railways and of the London-registered company that held the Buenos Aires gas supply monopoly) to accept appointment as Chief Security Officer at the Foreign Office, with the rank of Acting Assistant Under Secretary of State and direct access to the PUS. One of Will Codrington’s brothers travelled across Europe for Claude Dansey’s Z Organization under cover of being a film company executive.37
Codrington was unpaid. He had no staff until in 1944 he enlisted Sir John Dashwood, Assistant Marshal of the Diplomatic Corps, ‘the most good-natured, jolly man imaginable’ in James Lees-Milne’s description. Dashwood handled the security crisis at the embassy in Ankara, where the Ambassador’s Albanian valet Elyesa Bazna, codenamed CICERO, filched secrets and passed them to the German High Command. Codrington retired in August 1945, resumed his City directorships and accepted the congenial responsibilities of Lord Lieutenant of the tiny county of Rutland. It is hard to imagine that he and Dashwood scared anyone who mattered.38
Meanwhile Krivitsky had been summoned by the House Un-American Activities Committee (HUAC), then better known as the Dies Committee (named after its chairman, the Texan congressman Martin Dies). When he testified on 11 October 1939, naive and rude questions were pelted at him. One senator decried him as ‘a phony’, who ought to be deported. Krivitsky afterwards called HUAC ‘ignorant cowboys’ and Dies a ‘shithead’.39
There was a different assessment of Krivitsky in London. The star among Harker’s officers was MI5’s first woman officer Jane Sissmore: she had taken the surname of Archer after her recent marriage and was so precious to the Service that she had been kept in her job at a time when women civil servants were required to resign if they married so that they neither neglected their husbands nor continued to take a man’s place and salary. In November 1939 Archer convinced Harker that Krivitsky should be invited to London for debriefing. Krivitsky reached Southampton in January 1940, and was installed at the Langham Hotel in Portland Place under the alias ‘Mr Thomas’. Krivitsky’s four weeks of debriefing was MI5’s first experience of interrogating a former Soviet illegal about tradecraft, networks and names. As Brian Quinlan explains in Secret War, ‘The seamless nature of the debriefing’s planning and execution, the expertise and diligence of the officers who conducted it, and the quality and quantity of the information it produced have led some MI5 insiders to regard this case as the moment when MI5 came of age.’40
Krivitsky’s trans-Atlantic journey and accommodation in the Langham Hotel were tightly managed by his English hosts, who knew that a controlled but not oppressive environment improves the prospects of counter-intelligence interrogations. The FBI had waited nine months before interviewing Krivitsky and gave little forethought to the meeting. MI5 and SIS made meticulous preparations for his arrival at the Langham Hotel. They compiled preliminary character assessments of a kind that has since evolved and become standard operating procedure for defectors, foreign agents and foreign leaders. They exerted themselves to help Krivitsky’s wife and children, who were living in Canada while US immigration issues were resolved. Archer and her colleagues sought to impress Krivitsky with their understanding, competence and judgement. As Quinlan recounts, ‘their motivation was not simply pride; they understood that Krivitsky was a professional, and they hoped to gain his respect and cooperation by showing their own professionalism’.41
The debriefing was conducted by Archer, who was well informed about Stalin’s Russia and about Soviet espionage and approached Krivitsky from an international perspective. Her first task, which took several interviews, was to reassure him that he would not be arrested if he made admissions about spying on the British Empire. She then won his respect by her expertise in his field, and encouraged his explanatory candour by listening appreciatively to his account of all that he knew or had done. During debriefing, Krivitsky described the organization, tradecraft, tactics and personalities of the Fourth Department, the NKVD and the system of legal and illegal residents in the European capitals. He spoke of forged passports, secret inks, agent-training, penetration, counter-espionage and subversion in the British Empire. He predicted that in the event of an Anglo-Russian war the CPGB would mobilize a fifth column of saboteurs. Krivitsky made clear that the Stalinist aim was to support and fund colonial liberation movements, which would bring revolutionary change in
