Episode Title: The Zigzag Spy — The Bravado of Eddie Chapman
Season 1, Episode 2 — The Spies & Secret Wars
He was a safecracker. A criminal. A man who had escaped custody twice before the war even started. When Germany occupied Jersey in 1940, he didn't wait to be liberated — he approached the Abwehr and offered to spy for Nazi Germany.
They trained him for over a year. Radio operation. Sabotage. Parachute insertion. Document forgery. In December 1942, they dropped him into Cambridgeshire with orders to destroy one of Britain's most important aircraft factories.
Within twenty-four hours, he walked into a British police station and offered to work for Britain instead.
Eddie Chapman — code name Zigzag — went on to pull off one of the most audacious deception operations of the entire war. The Germans trusted him so completely they awarded him the Iron Cross. He was working to destroy them from the moment he landed.
In this episode, Amanda and Harry unwind the extraordinary story of the man who deceived both sides — and somehow came out the other end.

Welcome back to World War II Unwound here on the Best Story Publishing Podcast Network, where every story matters, every truth deserves to be told, and every question is worth asking. I'm Alan Best. Last week, Amanda and Harry told you the story of Juan Pujol Garcia, the man nobody wanted who built a fictional spy network from a kitchen table in Lisbon and helped save D-Day. If you haven't heard that episode, go back and listen. It is a remarkable place to start. Today we are going somewhere very different, where Garcia was principled, driven purely by conscience. This week's subject was a safecracker, a criminal, a man who charmed his way into and out of almost every situation life put him in, and who somehow became one of the most effective double agents of the entire war. His codename was Zigzag, and I promise you, by the time Amanda and Harry are done with his story, you will not know whether to admire him, distrust him, or simply stand back and appreciate the sheer bravado of what he did. I'll hand it over to Harry. This one is something else.
SPEAKER_02Thanks, Alan. Now imagine this. It is December 1942, the middle of the Second World War. A parachute opens over the English countryside in the dead of night. A man drops through the darkness, lands in a field in Cambridgeshire, and buries his parachute. He is carrying a German radio transmitter, a cyanide pill, a substantial sum of forged British currency, and orders from the Abwehr, Nazi Germany's military intelligence service, to infiltrate and destroy one of Britain's most important aircraft factories. He is, by any reasonable definition, an enemy spy on British soil. Within 24 hours, he will walk into a British police station and offer to work for British intelligence. What happens next is one of the most extraordinary, improbable, and genuinely dangerous intelligence operations of the entire war. Built around a man who, by every measure of conventional wisdom, should never have been trusted with anything more sensitive than a bus ticket. His name was Eddie Chapman, and nothing about his story is straightforward. Not his motives, not his methods, not his loyalties, and not the remarkable thing he ultimately did.
SPEAKER_00Harry, before we get into the spy story, I want to understand who Eddie Chapman was before any of this happened. Because from everything I have read, his pre-war life is not background detail. It is essential to understanding how any of this was even possible.
SPEAKER_02You are right to start there. Eddie Chapman was born in 1914 in a small mining town in County Durham in Northeast England. Working-class background, limited formal education, and from a very early age, an almost magnetic attraction to situations that most sensible people would avoid. By his early twenties, he had moved to London, fallen in with the wrong people, and discovered that he had a particular talent for a very specific kind of crime. He became a safe cracker. A professional one, working with a group that operated under the informal name of the Jelly Gang, named for their primary tool, Jellygnite, a powerful explosive they used to blow the doors off bank safes and post office strongboxes. Chapman was not the architect of the operation, but he became one of its most valued members for reasons that go beyond technical skill. He was extraordinarily calm under pressure. He was charming, funny, and utterly convincing in almost any social situation. And he had a quality that is genuinely rare, he could look at a complicated, high-stakes situation and think clearly while everyone around him was reacting emotionally.
SPEAKER_00And he had escaped from custody more than once before any of this?
SPEAKER_02Twice, before his final arrest. He was, by British law enforcement's assessment, infuriating, clearly intelligent, clearly capable, and absolutely committed to using those qualities in directions that cost other people money. By 1939, with war approaching, Chapman was facing serious charges and had fled to Jersey, one of the Channel Islands off the French coast, where he kept a low profile, acquired a girlfriend named Betty, and attempted to wait out his legal situation. He was arrested by Jersey authorities on the outstanding British charges and was sitting in a Jersey prison when, in June 1940, Germany occupied the Channel Islands. The only British territory to fall under Nazi occupation during the entire war. And here is where the story takes its first extraordinary turn.
SPEAKER_00And he approached the Germans.
SPEAKER_02Yes. While most people in his situation were focused entirely on survival, Chapman was thinking about opportunity. He calculated, with the same cold precision he had applied to safecracking, that offering to work for Germany was his most viable route to freedom. Not out of ideology, he had no particular sympathy for Nazism, no political convictions of any significance, it was a transaction, he had something the Germans might want: British connections, local knowledge, a criminal skill set, and they had the ability to get him out of a Jersey prison. The Germans were skeptical at first. A British criminal with a long record and no obvious intelligence value was not an immediately attractive asset. But Chapman was persistent and eventually persuasive, and in 1941, the Abwehr took him seriously enough to begin formal espionage training.
SPEAKER_00What exactly did that training involve?
SPEAKER_02Everything. Radio operation, the ability to transmit and receive Morse code messages on a clandestine frequency, which required considerable technical skill and an ear for precise timing. Sabotage techniques, how to place explosives for maximum structural damage, how to target power systems, industrial machinery, transportation infrastructure, parachute training, document forgery, cover identity construction. The Germans moved him between training facilities in France and Norway over more than a year, and by all accounts he was an exceptional student. His safe cracking background gave him a mechanical intuition that most trainees lacked. He understood how things were built, which meant he understood how they could be most efficiently destroyed. By late 1942, the Abwehr had decided Chapman was ready. His first mission was the De Havilland Aircraft Factory at Hatfield, north of London, one of Britain's most important production facilities for the mosquito bomber. His orders were to destroy the machinery that produced the aircraft. He parachuted into Cambridgeshire in December 1942. And within 24 hours, he had walked into a police station.
SPEAKER_00And not to turn himself in.
SPEAKER_02No, but to offer his services. There is a distinction, and it matters. Chapman did not confess and ask for mercy. He walked in, identified himself, told the police exactly who he was and what he was doing there, and then made a proposition. He wanted to work for Britain. He believed he could be useful. And he was prepared to demonstrate that usefulness immediately. The local police, understandably, had no idea what to do with him. He was transferred to MI5 within hours.
SPEAKER_00Harry, walk me through MI5's reaction. Because here is a man with an extensive criminal record, trained by the enemy, carrying enemy equipment, offering to switch sides. What does a professional intelligence service do with that?
SPEAKER_02They exercise extreme caution while simultaneously recognizing that what they might be looking at is extraordinarily valuable. The fundamental problem was verification. Chapman was telling them he wanted to work for Britain. But they had no way of knowing whether that was true or whether he was a plant, a German agent sent to penetrate British intelligence under the guise of defection. The Abwehr was sophisticated enough to run that kind of operation, so MI5 interrogated him extensively over several days, and what emerged was a portrait that was, paradoxically, more convincing precisely because it was so morally uncomplicated. Chapman did not claim to have had a change of heart about Germany. He did not invoke patriotism or conscience. He told his handlers with complete candor that he wanted his criminal record cleared, he wanted money, and he had calculated that his best chance of surviving the war lay with Britain, rather than Germany. That honesty, the absence of any heroic narrative, was exactly what made him credible. A German plant would have constructed a more compelling moral story. Chapman simply told them what he wanted and let them decide.
SPEAKER_00And they decided to use him.
SPEAKER_02Yes, they gave him a codename, Zigzag, which captured something essential about his nature, not straight, not predictable, operating in multiple directions simultaneously, and then they set about designing an operation around him that was, in its conception, breathtakingly bold. Chapman would do exactly what the Germans had sent him to do, he would sabotage the De Havilland factory, except that he would not actually sabotage it at all.
SPEAKER_00A fake bombing ingenious.
SPEAKER_02Yes. In one of the most remarkable theatrical productions of the Second World War. MI5, working with a team of experts that included a special effects technician from the British film industry, a man named Jasper Mascelline, who came from a family with a long tradition in stage magic and had applied those skills to military deception, set about making the De Havilland factory appear to have been comprehensively destroyed while leaving its actual production capability completely intact. The transformer housings were disguised with painted canvas to look as though they had exploded. Debris was carefully arranged around the exterior in patterns consistent with blast damage. Sections of the outer structure were scorched. Newspaper reporters, selected and briefed with great care, published articles describing a mysterious explosion at an unidentified aircraft facility somewhere in the home counties. German reconnaissance aircraft that flew over the site photographed what appeared to be the aftermath of a successful and significant act of sabotage. The mosquito bomber production line was operating throughout the entire period.
SPEAKER_00And Chapman reported back to Germany that the mission was complete.
SPEAKER_02Detailed, technically specific radio transmission confirming the destruction of the facility, timed and formatted exactly as the Abwehr would expect from a successful agent making a post-mission report. The Germans cross-referenced Chapman's account against their aerial reconnaissance photographs. The physical evidence matched the agent report. As far as Berlin was concerned, their man Fritz, Chapman's German codename, had delivered one of the most significant acts of sabotage on British soil in the entire war. The factory that made the mosquito was down. The intelligence service that had trained and deployed him had every reason to be satisfied.
SPEAKER_00What did they do?
SPEAKER_02They awarded him the Iron Cross, Germany's highest military honor, presented to a British criminal who had been working to deceive them from the moment he landed. Chapman had now accomplished something that only one other person in the history of the conflict had managed, and we spoke about him last week, one Poohole Garcia. He had received the Iron Cross from an enemy he was simultaneously working to destroy.
SPEAKER_00Here is what I cannot move past. Chapman has pulled off this extraordinary deception. He is safe. He is on British soil. MI5 has him. The logical thing, the safe thing, is to stay. Why does he go back to Germany?
SPEAKER_02Because going back was the only way to make the operation continue to produce intelligence of real value. A double agent who has completed one mission and then disappeared is useful once. A double agent who returns to his handlers, is debriefed, receives new tasking, and goes deeper into the enemy's confidence becomes invaluable over time. Chapman's relationship with the Abfair, the trust he had built, the credibility the fake bombing had established was an asset of considerable strategic value. Walking away from it would have meant sacrificing everything that had been constructed. And Chapman, characteristically, wanted to go back. This is one of the most important things to understand about him. He was not going back out of duty or patriotism. He found this life genuinely compelling in a way that ordinary existence had never matched. Not even the jelly gag had given him this. He was living at an intensity that he had never experienced before and had no interest in giving up. So in 1943, with MI5's full knowledge and agreement, Eddie Chapman was extracted from Britain and returned to German-controlled territory.
SPEAKER_00And I want to stay with what that actually means for a moment. He is walking back into the hands of the people he has been systematically deceiving. If the Abwehr has any doubt at all, any fragment of counterintelligence that has come in, any inconsistency in his cover story, any suspicion from a single officer, he is dead. Immediately and certainly.
SPEAKER_02Yes, and he knew this with complete clarity. German intelligence was not known for restraint in its handling of discovered double agents. Chapman had been debriefed by MY5 at exhausting length, his cover story examined from every conceivable angle, his account of his time in Britain rehearsed until it was as natural as memory. But no preparation fully equips a person for sitting across a table from a trained intelligence professional who is looking for reasons not to believe you. The margin between survival and catastrophe in that situation is measured in seconds and in voluntary micro-expressions.
SPEAKER_00How did the Germans receive him when he returned?
SPEAKER_02With a combination of celebration and methodical scrutiny, the Iron Cross was formally presented. There is something almost surreal about that ceremony, Chapman accepting Germany's highest military honour while knowing that everything he had told them was constructed. He was debriefed at length about his time in Britain, the social landscape, the mood of the civilian population, the physical details of the areas he had moved through, the state of British military preparedness as he had observed it. Chapman had been meticulously prepared for every question. He provided information that was accurate where accuracy served the deception and carefully calibrated where it could be shaped to British advantage. And while he was doing all of this, answering questions about Britain for the Germans, he was simultaneously observing everything around him. The personnel, the operations, the priorities, the anxieties of the Abwehr officers he dealt with, information that made its way back to MI5 through channels that had been established before his return.
SPEAKER_00He was collecting intelligence while being debriefed as an agent.
SPEAKER_02Operating on two levels simultaneously, with what appears to have been remarkable composure. There is a particular quality of nerve required to sit in a room with people who would kill you if they knew the truth, answer their questions convincingly, and file away everything they say for transmission to the other side. His primary abwehr handler, a man named Stefan von Groning, who had developed a genuine personal affection for Chapman during their relationship, later described him as one of the most naturally gifted agents he had encountered in a long career. The tragedy from von Groning's perspective was that he had no idea whose side that gift was actually serving.
SPEAKER_00And then Germany sends him back to Britain a second time.
SPEAKER_02In June 1944, the same month as D-Day, Chapman was parachuted back into Britain with new orders, new equipment, and fresh tasking from the Abfair. He contacted MI5 immediately upon landing. He was debriefed, the intelligence he had gathered in Germany was extracted and analyzed, and the question became what to do with him next, and here is where the story takes its final turn. By this point in the war, the double-cross system that MI-5 ran, the network of turned German agents feeding controlled false information to the Abwehr, was a sophisticated, carefully managed operation. Chapman was too independent, too inclined to improvise in ways that could not be fully predicted or controlled. MI-5 made the decision to stand him down. His active role as a double agent was finished.
SPEAKER_00After everything he had done?
SPEAKER_02After everything he had done. The official assessment in his MI5 file described him in terms that captured the essential paradox of his existence. A man of considerable courage and ability, fundamentally motivated by self-interest, whose self-interest had, for a critical period of the war, aligned almost perfectly with Britain's strategic needs. That alignment, not any conventional patriotism, was what had made him effective, and when the alignment ended, so did the operation.
SPEAKER_00What happened to Chapman after the war?
SPEAKER_02Entirely in keeping with the rest of it. He was not celebrated. His criminal record was not formally expunged, the promise of that outcome had been implied, but never delivered in writing. He returned to civilian life with no public acknowledgement of what he had done, and no financial security beyond what he could create for himself. He married Betty, the girlfriend from Jersey who had waited for him through the occupation and the war, and they had a daughter. He pursued various business ventures with the same energy and creative flexibility that had characterized his entire adult life. Some of these ventures were legitimate, some were not. He wrote his memoirs, which the British government initially suppressed on national security grounds. He gave interviews over the decades, told his story in various forms to various journalists. He died in 1997 at the age of 83. The full official acknowledgement of his contribution came only after his death, when his MI5 file was declassified and historians could finally piece together what he had actually done.
SPEAKER_0083 years old, he outlived almost everyone involved.
SPEAKER_02He did. And there is something fitting about that, given who he was, Chapman had always been, above everything else, a survivor. He had survived the Jelly Gang, the Jersey Occupation, German intelligence training, two parachute insertions into wartime Britain, and years of operating under conditions where a single error meant death. Surviving peacetime by comparison was something he was extraordinarily well equipped for.
SPEAKER_00What is the right way to assess him? Because I find myself genuinely uncertain. He was a criminal before the war, he was motivated by self-interest throughout, he went back to a complicated life afterward. And yet what he did mattered, genuinely mattered.
SPEAKER_02I think the honest assessment is that Chapman resists the categories we usually use for wartime figures. He was not a hero in any conventional sense. He was not a traitor. He was not a patriot. He was something more interesting and less comfortable than any of those. A man of significant ability and very flexible morality, who, at the moment that mattered most, made a choice that benefited the right side. Whether he made it for the right reasons, is a question that does not have a clean answer. But there is a line in his MI5 file that I think about often when considering what Eddie Chapman actually was. The assessment reads, in part, that he was a man who enjoyed life to the full, who lived dangerously, but who at the critical moment made the right choice. That phrase, at the critical moment made the right choice, is doing an enormous amount of work. It papers over the criminal record, the self-interest, the moral complexity of everything that preceded and followed that moment. But it is also not wrong. And perhaps, that is the most honest thing you can say about Eddie Chapman. At the critical moment, he made the right choice.
SPEAKER_00Which is more than most people are ever tested on.
SPEAKER_02Considerably more, and he passed.
SPEAKER_00Okay, two episodes in. And I keep thinking about the comparison between Garcia and Chapman because I think it tells you something important. Garcia was pure. He acted from conscience, from a genuine opposition to fascism, from a belief that one person could make a difference. You could make a film about Garcia, and the moral arc would be clean. He is the hero. Chapman is something else. He was a criminal before the war, and he went back to a complicated life afterward. He made his choices for self-interested reasons. The moral arc is not clean at all. And yet, what he did was real. The fake bombing was real. The intelligence he gathered in Germany was real. The Iron Cross he accepted under false pretenses while working to destroy the people who gave it to him. That was real. I think what I take from Eddie Chapman is something about the relationship between motives and outcomes. We want the people who do important things to have done them for the right reasons. And sometimes they did not. Sometimes the person who made the right choice made it for the wrong reasons entirely. And the outcome was the same. Eddie Chapman. The zigzag sky. Complicated from beginning to end. Before Alan wraps us up, last week I asked you which kind of motivation you find more compelling. The principled idealist or the pragmatic opportunist. I got responses. And they were genuinely interesting. Keep them coming. This week I want to push that question one step further. Eddie Chapman's MI5 file says he was a man who at the critical moment made the right choice. Have you ever made the right choice for the wrong reasons? And looking back, does the reason matter if the outcome was good? I genuinely want to know. Send your answer to beststorypublishing at gmail.com. These are the conversations this show exists to have.
SPEAKER_01And that's episode two of World War II Unwound. Here on the Best Story Publishing Podcast Network, Eddie Chapman, the Zigzag Spy, a man who contained contradictions so large that the only honest way to understand him is to stop trying to fit him into a category. At the critical moment, he made the right choice. That is more than most of us will ever be asked to prove. Thank you for being here. It means everything to this team. Visit us at beststorypublishing.com and send your thoughts, your questions, and your responses to Amanda's question to Beststorypublishing at gmail.com. We read every single one. Next week on World War II Unwound, we pull back the camera entirely. We move from the individual spy to the machine behind all the spies. A Victorian mansion in the English countryside, 10,000 people working in absolute secrecy, and one particular genius who built something that the Germans believed was mathematically impossible. The story of Bletchley Park, the Enigma Machine, and the intelligence operation that may have shortened the war by two years. Until then, keep asking questions, keep digging deeper, and never stop being curious. I'm Alan Best, and this is the Best Story Publishing Podcast Network.
