Prologue

T HE WORLD WAS going mad in the spring of 1939, or that’s how it seemed to Joan Bright. A jaunty twenty-nine-year-old with swept-up hair and a button-down dress, she had travelled to London in search of secretarial work, having just turned down a job in Germany as governess to the children of Rudolf Hess, the Deputy Führer of the Third Reich.

When she mentioned her need for employment to an old friend, he gave her a strange piece of advice. He said he could get her work if she ‘went to St James’s Park Underground Station at 11a.m. on a certain day, wearing a pink carnation’. He added that a lady would be waiting for her and would whisk her away for an interview.

Joan only half believed what her friend had said. Indeed as the day approached, she felt convinced that he was playing a practical joke. But she went to the rendezvous at the appointed time and, sure enough, there was the mystery woman. She offered a whispered introduction and pointed towards a red brick Edwardian mansion block in the distance, indicating that this was the building in which the job interview would take place.

Joan was led on a roundabout route to the building, passing through the maze of alleys and backstreets that lie between Broadway and St James’s. Her dizzy imagination went into overdrive. She convinced herself that the woman had chosen the route quite deliberately ‘in order to reach it unobserved’. 1 She still knew nothing about the job for which she was being interviewed, but had high hopes of acquitting herself well. She had previously worked at Chatham House, where her efficiency and discretion had left a deep impression on her colleagues.

Only as she was led up to the fourth floor of the residential mansion block did she realize that this was to be no ordinary job interview. She was ushered into an office that overlooked Caxton Street and introduced to a military officer by the name of Chidson, ‘short, ginger and very precise’. 2 He gave a cursory introduction and then slid a sheet of paper across the desk and told her to sign it. She was too nervous to ask what it was. She simply scribbled her name at the bottom and handed it back to the colonel. As she did so, she noticed that she had just signed the Official Secrets Act.

Colonel Chidson took the paper, fixed his steely eye on Joan and asked if she knew why she had been brought to Caxton Street. When she shook her head, he told her that she was being interviewed for a job so secret that she would be tortured if she were ever to be captured by the Germans.

Joan was completely lost for words. She had been expecting to be tested on her typing skills, her shorthand and her ability to make a good strong cup of tea. In the silence that followed, Chidson got up from his seat, beckoned her over to the window and pointed towards a shadowy figure standing on the corner of Caxton Street and Broadway.

‘He has been there all morning, watching,’ he said. ‘When you leave here, don’t let him see you; turn left and keep going.’ 3

Joan had not yet been offered a job, at least not formally, and yet the manner in which the colonel was speaking suggested that she had already been accepted. He asked her to be seated and once again reiterated that ‘very dreadful things’ would happen to her if she were to be caught by the Germans. This time, he was rather more specific. ‘You will get needles up your toenails.’ 4

Half of her wanted to treat the whole thing as a grand hoot, one to recount to her flatmate, Clodagh Alleyn, later that evening. Yet Colonel Chidson remained cold and unsmiling throughout the interview, which Joan took as a sign that he was in deadly earnest. She also knew that in the newspapers and on the wireless the talk was of nothing but war.

Just a few weeks earlier, on 15 March, Hitler had scored his latest coup by marching his storm-troopers into Bohemia and Moravia. In doing so, he completed his annexation of what had previously been Czechoslovakia. The German soldiers met with so little resistance that a jubilant Hitler was able to travel to Prague on the following day and proclaim a new addition to the Third Reich. Henceforth, Bohemia and Moravia were to be a German protectorate, firmly under the rule of Berlin. Although Britain’s Prime Minister, Neville Chamberlain, insisted that Hitler’s annexation was not an act of aggression, there were many in the country who felt that his policy of appeasement had passed its sell-by date.

Joan was among those who felt a deep sense of unease, worried that Britain was being dragged into a conflict for which it was woefully ill-prepared. But when she weighed up everything that she’d been told by Colonel Chidson, the prospect of full-time employment and a generous salary overrode all her fears about the future. Besides, she was young, unattached and fancy-free. And a strange job in a strange office might just add to the gaiety of life. She convinced herself that it was all ‘good clean fun’ and thanked the colonel for what she assumed to be the offer of employment. She promised to show up for work punctually on the following morning.

Although she would have never admitted it to Colonel Chidson, she was rather excited to be joining an office ‘in which fact and fiction played so smoothly together’. 5 Yet she couldn’t help but quicken her pace as she emerged from the building into Caxton Street, and she studiously avoided catching the eye of the mysterious man who was still standing on the street corner.

Joan would have to wait another twenty-four hours before learning what her new occupation entailed. In the intervening time, she could do little more than ponder over the strange situation in which she found herself. She felt torn between happiness at having a job and a vague sense of unease at what that job might involve. It was as if someone were leading her into a bizarre twilight world in which all the cherished norms had been subverted.

Joan Bright was not alone in finding her world turned upside down in the spring of 1939. Sixty miles to the north of London, in Bedford, a caravan enthusiast named Cecil Clarke was tinkering in the workshop behind his house at 171 Tavistock Street when his wife summoned him to the telephone. There was someone who wanted to speak to him.

Clarke took the receiver and found himself having a conversation that was as strange as it was unexpected. The person at the other end was not calling about caravans, that much was clear. Nor was he enquiring about the new anti-rolling suspension system that Clarke had recently invented. Clarke tried to probe the caller for more information, but the man declined to reveal why he was calling and was, by his own admission, ‘very guarded’ 6 when Cecil asked as to his identity. All he would say was that the two of them had met a couple of years earlier, and that he would be paying a visit to Tavistock Street on the following day.

Cecil Clarke hung up the phone, still puzzling over the caller’s identity and utterly perplexed as to what he might want. But in common with Joan Bright, he had a vague sense that his life was about to take an altogether more exciting twist.

In that, he was correct. The visit on the following day was to change his life.
