The Counter Intelligence Corps was an intelligence branch of the United States Army, and after the war it was involved in recruiting Nazis – especially scientists – to work for the US. There is no question that as the Second World War ended, both the United States and the Soviet Union quickly switched their focus to each other, hence both sides’ recruitment of Nazis to work for them.

Likewise, the Field Security Section existed during and after the Second World War as part of the British Army, with a security and intelligence function in areas occupied by British forces.

Readers may wonder whether I have stretched credulity with apparently respectable British citizens aiding the Nazis during and after the war. They may feel that in particular the character referred to as ‘the Admiral’ is especially unlikely. In fact there was an Admiral Sir Barry Domvile, a former Director of Naval Intelligence and such a prominent Nazi sympathiser that he was imprisoned under wartime regulations for three years from July 1940 to July 1943. Domvile was involved in shadowy organisations such as the Link and the Right Club, which were characterised by their pro-Nazi sympathies and virulent anti-Semitism. Together they claimed thousands of supporters, only a small number of whom would have been detained under Wartime Regulation 18B.

Cork Street in London’s West End – where the fictional Bourne and Sons is located – is the centre of the capital’s commercial art galleries. There is no known connection between the street and Nazi spy rings.

There are frequent references in the book to sums of money in pounds sterling. To get an idea of the value of these sums today, I rely on the Bank of England website. As a ready reckoner, £5 in 1945 would be worth approximately £217 today, equating to €243 or US$275. Other currencies are, as they say, available.

I’d like to express my sincere thanks and appreciation to the many people who’ve helped bring about the publication of this book, not least my agent Gordon Wise at Curtis Brown, who has been enormously supportive over a numbers of years. My publishers Canelo have done a fantastic job with the Prince series, and also in republishing my Spy Masters novels. End of Spies was the second book in the Prince series that I wrote during the COVID-19 crisis in the UK, but Michael Bhaskar and Kit Nevile and the whole team at Canelo remained attentive, professional and helpful throughout. Thanks too to Jane Selley for her skilful copy-edit, and to the many people who helped me with aspects of the book and answered seemingly odd questions as I was writing it.

And finally to my family – especially my wife Sonia, my daughters and their partners and my grandsons – for their encouragement, understanding and love.
