But there are some ‘facts’ on which most historians and biographers can agree, and by listing them baldly, the picture becomes a little clearer.
The Duke and Duchess of Windsor were married at a chateau belonging to Charles Bedaux in 1937. The duke pointed out the weaknesses in the French lines around Sedan in reports to the British general staff in late 1939. The duke dined with Charles Bedaux several times in Paris in autumn 1939. Charles Bedaux visited the Netherlands in the winter of 1939 and 1940 where the British secret service became suspicious of him. The German ambassador to the Netherlands thought the Duke of Windsor was unhappy with the British government and might provide intelligence to the Germans. The Germans changed their invasion plans to attack through the Ardennes rather than central Belgium. Charles Bedaux is mentioned in the Abwehr files as one of their ‘V-Men’; that is, an agent. In 1942 he was arrested by the French in Algeria, and shipped to America, where he committed suicide in 1944 while waiting to be tried for treason. From 1939 to 1940 British intelligence became increasingly concerned about the loyalty of the Duke of Windsor. In the summer of 1940, Winston Churchill, one of the duke’s most loyal supporters when he had been king, insisted that the duke take up the post of governor general in the Bahamas. According to a paper drafted by Lord Lloyd at the time, this was because of fear of the duke’s well-known pro-Nazi attitudes and the possibility of intrigue growing up around him.
There is an absence of conclusive documentary evidence of the duke’s treachery. But there is ample evidence that documents relating to the duke have been hidden or destroyed by the British government.
Was there a conspiracy to overthrow Churchill’s government and replace it with a pro-German puppet government? Another difficult question. There were many Establishment figures who wanted to end the war in 1939–40. These included Rab Butler, Lord Tavistock, Lord Beaverbrook, Richard Stokes, Samuel Hoare, Oswald Mosley, Captain Maule Ramsay, General Ironside, David Lloyd George and, in late May 1940, Lord Halifax. Some simply believed any war was wrong. Some wanted to win the war, but believed facts had to be faced: it was better to negotiate peace terms rather than lose it. And some admired Nazi Germany and preferred her as an ally rather than an enemy. All considered themselves patriots. Some, like Lord Oakford in the novel, were confused by these differing motivations.
The role of Lloyd George is an interesting one. Although seventy-seven, he was the most viable alternative to Churchill, Chamberlain and Halifax as Prime Minister, and indeed had served as such in the First World War. He had visited Hitler in Germany and the Duke of Windsor in the south of France and declared himself an admirer of both. According to his secretary, as quoted by John Lukacs in Five Days in London, the reason he turned down a position in the War Cabinet in the summer of 1940 was that he ‘was not going with this gang. There would be change.’
In France in June 1940, Marshal Pétain became the leader of a French government based in Vichy, which collaborated with Germany. Although vilified by history, at the time the 84-year-old soldier was seen as a true patriot, and a hero of the Great War. If Pétain could become President of Vichy France, it is not beyond the realms of possibility that Lloyd George and the Duke of Windsor could have been prepared to lead an equally subservient Britain.
Something was going on. I don’t know what it was — it may be that no one still alive does — but something was going on.
Sir Henry Alston, Lord Copthorne, Lord Oakford, Major McCaigue and Constance Scott-Dunton are fictional characters, although they share many traits with real pacifists and pro-Nazis of the time. There were many men and women who were pro-Nazi in 1938 and genuinely realized the error of their ways in 1939, such as poor Lord Redesdale, Nancy Mitford’s father, who concluded that ‘abroad is unutterably bloody and foreigners are fiends.’ He fell out with his still pro-German wife, and removed himself to a Scottish island where he died a broken man. Without proper evidence I am reluctant to accuse real individuals such as him of treachery, so I have preferred to create fictional equivalents.
The Abwehr, the German secret service, was consistently opposed to Hitler before and during the war. Admiral Canaris was arrested for his part in the plot to assassinate Hitler in 1944 and was executed in 1945. The implications of what it means if a nation’s secret service is opposed to that nation’s government in war have not to my mind been fully explored, although Richard Bassett’s book Hitler’s Spy Chief makes a start. The ‘little W.C.’, as Canaris called himself, was a big admirer of ‘the great W.C.’. Theo is a fictional character, but representative of a number of young German lawyers who became involved in the opposition to Hitler, including Fabian von Schlabrendorff, Peter Bielenberg, Adam von Trott, Hans-Bernd Gisevius and Helmuth von Moltke.
Any novel set in the Second World War presents the writer with a seemingly unending list of books to read, but it is worth mentioning the most useful ones here. On the Venlo Incident there are accounts by Sigismund Payne Best (The Venlo Incident) and Walter Schellenberg (The Schellenberg Memoirs). Both were spies, and hence professional liars, and both had reputations to protect. The two sources conflict, and while trying to reconcile them I realized that it was possible not only that one was right and one was wrong, but that they could both be incorrect. This was an important lesson for all sources on this subject. Dieter von Hertenberg’s diary entries are based on General Guderian’s account of the Blitzkrieg in Panzer Leader. The patrons of the Russian Tea Rooms and other dodgy pro-Nazis are described in Patriotism Perverted by Richard Griffiths. The intricacies of French and German war plans are untangled in Ernest May’s Strange Victory. The precarious position of the British government in May 1940 is the subject of John Lukacs’s book Five Days in London, and is thoroughly addressed in Andrew Roberts’s biography of Lord Halifax, The Holy Fox. Philip Ziegler’s King Edward VIII provides a sober antidote to Martin Allen’s Hidden Agenda, and Sol Bloomenkranz’s e-book Charles Bedaux — Deciphering an Enigma comes close to doing just that.
I have tried to tamper with historical events as little as possible, but in the interests of novelistic clarity, I have made some minor manipulation to dates. For example General Guderian was given the order to take up a new command on 29 May 1940, not 28 May, and the duke fled Paris for Biarritz a little later than 22 May. Also I have simplified the tangle of security organizations which reported to Heydrich — the Sicherheitsdienst, the RHSA and so on — to ‘the Gestapo’.
Finally I would like to thank a number of people for their help: Robin Reames, Hilma Roest, Lisa van de Bunt, Theo Kes, Kate Howles, Sander Verheijen, Richenda Todd, my agent Oli Munson, and Nic Cheetham and his colleagues at Head of Zeus. I also need to thank my wife and children for putting up with a husband and father who has spent much of the last couple of years hiding from the twenty-first century in his own little phoney war in Holland and France seventy-five years ago.
