Vatslav Yeleneck plods through freezing fog and pavements slippy with snow slush. The streetlights cast an eerily amber glow, but Yeleneck is in no mood to appreciate the scene. He's just finished a long shift. waiting tables at the Hilton Hotel. All he wants is a hot bath and his bed. He turns a corner and stops sharply. Ahead is a woman in her mid-50s with short wavy grey hair and wearing a long

cream coat. She hasn't seen him. She seems lost in her own thoughts, but he recognises her instantly from the photo she sent him. It is Johanna van Harlem, his son. He's supposed biological mother. Yelenek's Czechoslovakian spymasters have discovered that Johanna has been tirelessly searching for her son Irwin. She gave him up for adoption when he was just three months old. Now, she thinks she's found her long-lost child. She has no idea Irwin's identity is being used by Yeleneck as cover for his spying in the UK.

To maintain his cover as Irwin, Yeleneck. Yeleneck's spymasters have decided he must meet with Johanna and pretend to be her son. But nothing can be allowed to endanger his cover. If Johanna becomes suspicious or is unconvinced, then he needs to get rid of her by any means necessary. Yeleneck flexes his knuckles. He's not scheduled to meet Johanna until tomorrow evening. Perhaps this is fortuitous if he needs to displace. of her body, there is poor visibility on the streets, and he's close to his apartment.

He approaches Johanna. Excuse me, but are you, Mrs. Van Harlam? Johanna whirls around. I am. I'm Irwin, your son. Johanna gasps in surprise as she stares at him. Yellowneck tenses, ready to strike. Alice and Matt here from British Scandal.

Matt's some news for you. British Scandal is going to Broadway. What? Sorry, not literally. I just mean we're taking it to the stage. Is this your festival crossed wires? Where all the UK's biggest podcast do live shows across iconic venues in Sheffield

between the 2nd and 5th of July. That was a beautiful read. Matt and I cordially invite you to our British Scandal live show on Sunday July the 5th. And if we're doing the story, I think we are. It is potentially one of the most ridiculous scandals we've ever told.

So grab a ticket at crossedwires. Live. That's C-R-O-S-S-E-D-Wires. I'm Amelia Fox, and this is The Spy Who, an audible original. In the last episode, Vatslav Yelanek was trained as an elite, illegal spy for the Czechoslovakian intelligence service, the STB. He was given a new identity, one that had formerly belonged to a boy who was later adopted. Now Yeleneck has been trained. tracked down by the boy's biological mother.

If he cannot convince her he is her long-lost son, he must eliminate her, so she doesn't blow his cover. You're listening to The Spy Who Stole a Son. This is episode two, a dangerous reunion. January 3rd, 1978, South Kensington, London. Johanna gasps in surprise at the handsome man who has just introduced himself as her long-lost son, Erwin. He leans in and gives her the three-kissed Dutch greeting.

Hello, mother. Hearing him call her mother triggers a flood of emotion. She throws her arms around him, holding him close. Irwin, at last! She feels tension leave his body and realizes he must have been as nervous as she was about this meeting. He smiles. My flat is close by. Should we talk there in the warmth?

He offers his arm. For a moment, Johanna hesitates, worried about her other son, Hans. He is the teenage child from her failing marriage. She wanted him to meet his new half-brother, but he's back in their hotel room sleeping. She takes Irwin's arm and nods. Perhaps it is better this. This first meeting is just the two of them.

As they enter his flat, he moves to put the kettle on while she walks around looking for family photos and mementos. There are none. The only picture on the wall is a calendar of naked girls. Do you have a girlfriend? No. Tea or coffee? Coffee, please. Do you have any family photos I could see?

I'd love to see this. them. I think I have some of me as a child somewhere. Let me check. Yellinek finishes making the coffees, then scrabbles about in a cupboard. Here we go. The top one is my first day of school. Oh, look at you. So sweet. I wish I could have been there. Yohanna's eyes missed over as she flicks through the photos, but there are none with his adoptive parents. What were they like? Your adoptive parents? Did they treat you well? Were you happy? These are questions that have consumed Johanna every day since she gave her son up. She has nightmares that she handed him over to abuse or trauma. I was fine. They were nice. She waits for more

detail, but it doesn't come. She feels anxious. Is he hiding something? He seems to sense her unease. He abandons the photos and instead finds and hands over a document. Look, I've kept this always, because it had your handwriting on it. It is the adoption paper she signed all those years ago in the Netherlands. Her face crumples. I never wanted to sign it. I was so young with no money and a cruel father.

Erwin, do you forgive me? He puts a reassuring arm around her. Of course, it must have been very hard for you. After a few moments, he pulls back and stands. Let's have some champagne. We shouldn't be sad tonight. We should celebrate. Yes, this is the happiest day of my life.

To long-lost family, To my handsome son. They clink glasses, but as Johanna smiles up into Irwin's face, she suddenly notices his eyes are brown. The baby she gave up for adoption had blue eyes, just like herself and his father. She shakes off the doubt. She's heard a baby's eyes can change colour, and he has the adoption certificate. This is, without doubt, her son. A few days later, Victoria Street, London.

Yelinek walks home, lost in thought. Johanna and her son Hans have returned to the Netherlands. Their visit has made him miss his own family. He is beginning to realize the scale of the sacrifice he agreed to for this job. He idly stops outside a famous seafood restaurant, wondering if an expensive dinner will improve his mood. A pretty girl stops beside him. She inspects the specials chalkboard, which is advertising fresh oysters.

He brightens. He may not be allowed a family, but he is allowed liaisons with beautiful women. He smiles at her. Have you ever tasted fresh oysters? She looks surprised at a stranger addressing her, but she smiles back. No, never. Have you? Whole bucket loads. They're amazing. You must try them. It's a lie. Yeleneck has never eaten oysters in his life, but he's heard they're an aphrodisiac, and that's all that matters now. Would you join me for dinner? I would be honored to buy you your first oysters. She hesitates, but his well-cut suit and handsome face seemed to convince her. All right. Thank you.

guides them to a table and Yelenegh orders a dozen oysters for both of them and a bottle of expensive white wine. It doesn't take long for a huge silver platter to be placed in front of them. For oysters. His date claps her hand joyfully. Oh, they look glorious. He has to agree. On a bed of crushed ice and decorated with lemon wedges is a huge pile of oysters still in their elaborate shells. Yelinek picks up a shell and grabs a small round ceramic dish in front of him. He assumes it has been made specially for oyster eating. It holds the shell perfectly.

He squeezes some lemon on it and gulps down the shellfish with the aid of a small fall. It's delicious. Even better, the girl is proving to be both witty and gorgeous. He soon forgets his early. depression. But when the waiter leaves the bill on the table, his heart skips a beat. It's the most expensive meal he's ever eaten. Too late now. Hoping to impress his date, he nonchalantly places cash on top and signals the waiter to collect it. Keep the change. Thank you, sir. Also, do you have an ashtray? The waiter hesitates. He says, he, he,

He points towards the small round ceramic dish now filled with remnants of Yelenex oysters. This isn't ashtray. Sir was so good as to have eaten his oysters from it. Yellenex's cheeks burn with embarrassment. His date cannot keep a straight face. Eaten whole bucket loads of oysters. He brushes it off with practice charm that it conceals anxiety. He was caught out in a lie.

It may not mean much tonight, but it's a reminder of how easily it can happen, especially now he has an inquisitive and attached mother in his life, threatening to poke holes in his cover identity. Spring 1978, the Netherlands. Gellinette approaches a small bungalow surrounded by a lush, orderly garden. He adjusts his grey suit nervous. She said nervously. Johanna has organised a party for all her extended family to meet her long-lost son.

It will be the biggest test yet of his cover identity. Johanna opens the door. Oh, you're finally here. Everyone, Irwin is here. She hugs him with difficulty, as he is also carrying a large box of champagne bottles. I've brought a gift for everyone. I hope you like Moe, eh? There's more in the car.

Erwin, come and meet everyone. This is my sister, Rie, and her husband. And these are my brothers. Yeleneck smiles and kisses the numerous cheeks of his newfound family. They examine him with curiosity. Goodness, doesn't he look like Steve? Yeleneck relaxes a little. It's going well.

He smiles at Yohanna's cheek. teenage son has, but gets a glowering look in return. After initially being overawed, Hans has become jealous of him. Yelenex smiles at the irony. If only Hans knew how alike they were in wishing Johanna would stop lavishing so much attention on her long-lost eldest son. He sees Johanna heading towards him and tenses. Owen, I was thinking how much I would like to meet your adoptive parents. Yelanek groans inside. He was not given enough information in his cover story for this. He needs to give as little detail as possible so he doesn't get tripped up later. I'm afraid they're dead. You never told me that. I didn't think you'd be interested.

Johanna looks frustrated and upset. He knows she thinks he is hiding an unhappy childhood from her and it's triggering her own guilt and trauma. He's unmoved by the knowledge. Better that than endangering his cover. Yohanna shakes off her upset and grabs a camera. Let's get a family photo of you with everyone. Oh, and I must have one of you and Hans together. Yelanik nods reluctantly.

He's supposed to avoid photos, but it would look suspicious not to. His cover identity is rapidly. going from useful protection to his biggest threat. Say cheese. A few months later, Prague. Yeleneck sits in an STB safehouse and folds his arms sulkily. He's been unexpectedly recalled to Czechoslovakia

and is now being harangued by two senior officers over his lavish spending. You're not producing much useful intelligence, despite all the money we send you. That's because my mission is totally unrealistic. as I have already told you. A younger officer, only just senior in rank to Yeleneck, sifts through his expenses claims. What could you possibly need two cases of expensive champagne for? You want me to pretend to be this woman's son?

Well, people ask fewer questions when you're spending money on them. Or perhaps you were too used to the decadent Western lifestyle. Maybe you have forgotten what you were fighting for. Swallows his anger with difficulty. Falling out with his bosses won't do him any favours. I have sacrificed my very identity for the cause of real socialism. My commitment has never wavered. Am I allowed to visit my parents while I am here?

No. But we will keep you updated by the usual channels. With a sour expression, the younger of... The officer slides a briefing folder across the table to Yelenek. Since you seem unable to infiltrate the royal family, perhaps you will do better with this new mission. Yeleneck flicks through the briefing document. Refusenix.

Traitorist Jews who want to leave the Soviet Union to go to Israel. They are engaging in dissident activity, trying to force the Soviets to give them visas. Many are a significant security risk. Our comrades in Moscow want our help in dealing with them. Yelanek leaps through the file and the first officer leans forward. You will infiltrate the Jewish organizations in the UK that are trying to help the refusenics. The KGB needs to know who they're helping and how.

Yelenex excited. He doesn't yet know how he's going to infiltrate them. But he already knows it will be easier than planting bugs inside Buckingham Palace. Several months later, 1979, Golders Green, North London. On a busy high street, Yeleneck eyes the disused laundrette in front of him. There's a musty smell escaping the boarded-up windows, and the whole building needs repair. He knocks on the door at the side.

It's soon opened by a tall woman with a fashionable hairstyle and tinted glasses. Can I help you? I'm Erwin Van Halem. I phoned about your advert, the one looking for volunteer Russian speakers. Oh, I remember. I'm Rita Aker. Pleased to meet you. Come on up.

He follows her up the narrow stairs to a floor littered with half-opened boxes, desks and filing cabinets crammed into any space that's... can fit them. Everywhere, women are typing on the phone or filing. Aker grins at his expression. Excuse the mess. We're only here temporarily. I know it doesn't look like much, but you'd be surprised at the contacts and influence we have. What do you know about us? You're the women's campaign for Soviet Jewry, and I think you were the chairwoman. I am. Most people call us the 35s, though. Oh?

Because all of us who founded it were 35 at the time. Weird, huh? It's certainly a memorable name. If it's memorable, all the better for highlighting the plight of Soviet Jews. They aren't dissidents. They simply want to practice their faith. For that, they're thrown in prison or psychiatric units. I agree.

It's inhuman. I'm not Jewish myself, but I want to help if. I can. Yeleneck can see Akerus instantly more wary, knowing he's not Jewish. So, how come you speak Russian? I grew up in Czechoslovakia. Really? But your name? It sounds Dutch. Well, it's actually an interesting story. My birth mother is part Jewish and Dutch. Yelenek launches into the tragic story of Yohanna and how she was forced to put him into an orphanage in Czechoslovakia. He finishes with their emotional reunion a year ago. By then, Aka has tears in her eyes.

That is extraordinary. Girls, come hear this! The other women eagerly crowd round him to hear him retell the story. Watching their rapt expressions, Yeleneck knows all suspicion of him has faded. Johanna might be a problem for his spy mission, but today, she just became a problem. became his key to infiltrating Soviet refusenics. A few months later, offices of the 35s, Golders Green, London.

Night, Irwin. Night. As the clock on the wall ticks past 9pm, Yeleneck is now alone in the offices of the 35s. The women here trust him now, and he's used his work at the hotel and long commute from West London as a reason for doing his volunteer work at odd hours. Now he's got the chance he's been waiting for.

He opens up some of the large filing cabinets and starts rifling through them. He grins as he does so. Aker was right. The 35s are well connected. There are details for MPs, lords, American politicians and Canadian activists. But the most valuable find,

a long lists of refusenics in the Soviet Union complete with names, addresses and their letters pleading for help. He takes out his sub-miniature spy camera and starts snapping photos. Information he sure will delight his bosses and help the KGB root out the dissidents. Five years later, 1984, Silver Birch Close, Friand Barnett, North London. Johanna Van Halem and her son Irwin sit at a small table eating dinner.

She looks around proudly. He's now the Hilton Hotel's purchasing manager and has bought this new two-bedroom flat. It's a lovely flat, but you still haven't put any family photos up. Irwin rolls his eyes. Mother, I am 40 years old and a man. I don't need to be surrounded by family. family photos. For the last six years, Johanna has visited Yelanik twice a year and phoned him every week. She loves him dearly, but there have also been many arguments. She can't understand why he's

always so closed with her. She feels like she knows little more about him or his life than when they first met. Why did you never try to find me? Yelanik looked surprised at her abrupt question. He fiddles with his fork for a moment. I knew my father was a Nazi, and you had given me up for adoption. I didn't want to go there. Tears fill her eyes. She tries to blink them away. Look, I'm sorry.

I thought you'd abandoned me. He clears their plates and starts washing up. To distract herself, Johanna takes a dish towel and starts drying the dishes. They work for a few minutes in silence until she attempts to put some glasses away in a cupboard. Don't do that. What?

I've told you before. I don't need help, and you're never to open any of my cupboards. She shrinks back in the face of his threatening expression. It fades quickly. I'm sorry. It's been a stressful week. Go, put your feet up.

Let me look after you while you're here. Johanna puts the dish towel down, feeling the tears threatening again and retreats to the sitting room. She wonders why she can't stop asking questions when she knows it upsets him so much. But it's a compulsion. She has to know the truth. As she sits on the sofa, she wonders if there is a way to find out without asking him. Perhaps a trip to Prague to see the places he lived as a child will help her understand him. him better. September 1985, a year later, Enfield, North London.

Yelanick is in the house of Dr. Michael Kami, a GP and supporter of the 35s. Around them are suitcases filled with clothes and Hebrew prayer books. Dr. Kami is planning a covert trip to Moscow to visit Refusenix, and he's asked Yelanik to accompany him as his translator. Another supporter who's been to Russia before, Hans Yelenik, a magic slate toy. It's a piece of rigid cardboard covered in wax and topped with a translucent plastic sheet. Children can write messages on the slate, but when they lift up the plastic sheet, the writing magically disappears. The KGB will have you under surveillance. Assume everywhere is bugged.

If you need to say anything related to the mission, then write it on these. ease. Yelanik nods soberly, but is secretly enjoying the irony of being instructed on tradecraft by this amateur. Dr. Kami enters the room. He's middle-aged with a long beard and sympathetic eyes behind his glasses. In his hands are three large plastic bags bulging with prescription drugs. Yelanick, France. What are those for? We're taking medicines with us that are scared. or not allowed in the USSR. We cannot possibly claim that much as for personal use. We'll be arrested.

Dr. Kami grins at Yelanik. Relax. I'll brief you on the many medical conditions you have. And if we're arrested, we'll create an international incident. It will bring some much-needed publicity to our cause. Yelanik is worried. The last thing he needs is the world's media, focused on himself.

He's also under strict orders to maintain his cover at all times, even if that means getting arrested and sent to a Moscow prison. His golden spying opportunity is fast losing its shine. October 1985, Cheramietjeva Airport, Moscow. Yelanek and Dr. Kami stand in the long passport queue in the dark. Their plane arrived late at night and the only life, and the only lights that are on are directly above the passport booths.

Electricity is scarce in the USSR. Yelanik whispers to his companion. Remember, don't make eye contact or initiate conversation with the border guards. They will use the smallest reason to take you away for questioning. Don't worry, I know what to do. They reach the front of the queue.

Yelanik has his Dutch passport, stamped and waved through without incident. Once through, he waits for Dr. Kami. The doctor is beaming jovially at the passport officer. Good evening, comrade. Yelanik watches with growing fear, as the passport official questions Dr. Kami. There's nothing he can do except wait.

But if Dr. Kami gets arrested now, it'll be prison for both of them. October, 1985. Moscow. Yelanik and Dr. Kami walk into a small pharmacy and join the long queue of customers. They got through border control without incident. Now, he and Yelanik are meeting the head of the Jewish pharmacist's underground network to hand over the smuggle drugs that will only be offered to Jewish patients. Yelanik notices the pharmacist often shakes his head regretfully and And most customers leave empty-handed.

On seeing them and Dr. Kami's briefcase, the pharmacist nods to a woman in the back office. She instantly moves to the door and stops anyone else entering the shop. When the last customer is left, she locks the door. The pharmacist in his long white coat smiles at them. Welcome. I am so pleased to finally meet you. Dr. Kami hands over the briefcase with a list of the drugs that are inside. The pharmacist stows it in a concealed spot beneath his counter

and then ushes them upstairs into his flat. Over tea, he tells them the network is expanding, but he's being watched, so it's difficult for him to recruit others. Dr. Kami reveals that part of his mission while in the Soviet Union is to recruit more doctors into the network and that he has a list of people to approach. Yelanik makes a mental note to get hold of that list. He's got a secret meeting with the KGB tonight,

and they will want to know every name on it. Two nights later, Chenifzzi, the Soviet Union. Yelanik walks beside Dr. Kami through misty rain, pleased to stretch his legs after spending a day and two nights on a train. Where are we going? We're visiting Mark Grower. He is a refuse Nick we've lost contact with.

He lives in that tall grey building. You need to knock on the door of apartment number 16. Me? You're not coming. Dr. Kami's usual joviality gives way to an anxious frown. You look less Jewish than me. You'll attract less suspicion. Yelanick nods.

During this trip, he has been surprised at the level of anti-Semitism they've experienced. Jews in the USSR are expected to abandon all outward signs of their faith and integrate into an atheist society. Otherwise, they lose their jobs and are abused by neighbors. Yelanik crosses the road, enters the apartment building, and climbs the stairs to the top floor. There's no answer. And the bell doesn't seem to work either. Across the hallway, a door creaks open and a tiny old woman in a black dress and headscarf

scowls at Yerlinik. They took him away. Why? For spying, he was a Jew and an enemy. She folds her arms and peers more closely at Yelanik as if trying to memorize his features. Yelanik instantly. turns his back on her and leaves. As he returns to the street, Dr. Kami is alarmed at seeing him

hurry back. What is it? We need to go. Now. Yelenik tries to pull Dr. Kami away, but the older man flings off his hand. What happened? Shh, he's been taken. This place is probably being watched. We need to find out what happened to him. We need to raise his case back home. Yelanen. Grinds his teeth at the doctor's stubbornness, he cannot afford to be arrested by some KGB officer who doesn't know he's on their side. He grabs Dr. Kami by his shoulders. Listen to me, if you're not careful, we will be joining him in his cell in the Lubeianka. The Ljanka is the KGB's headquarters and where all suspected dissidents are taken for interrogation and often torture. Dr. Kami looks frightened.

He finally nods and they hurry back to the train station. Five months later, 22nd March, 1986, Stierkoli, a small village near Prague. In a luxurious safe house, Yelenik admires the original artwork on the walls. His recent trip to Moscow proved a major success and exposed the Jewish Refusnik network in the USSR. One of his Czech bosses watches watches him. Is this the kind of thing you'll sell in your new business? In the wake of his success, his spymasters at the STB have agreed Yelanik can leave his busy job at the Hilton Hotel and start an antique art dealership. Not only will it give him more time for spying, but is an ideal way to launder his spy pay and expenses.

Yelanik has taken an art course in preparation and hopes he sounds more confident than he feels. No, it's out of my league. It's an original Shepala. The conversation is interrupted by the arrival of a black car. Yelenik is amazed to see the director of the KGB, Viktor Chebricov, get out of the car. On entering, Chebrikoff smiles and holds out his hand to Yelenik. Ah, a man of the moment, comrade Yelenik.

Chebrikoff nods to one of his colleagues who steps forward. with an embossed and gilt-edged presentation box. Inside is a medal featuring a red enameled star, a shield and crossed swords. Chabrikov pins it to Yelanik's chest with a smile for your outstanding service in strengthening our brotherhood in arms. Yelanik blinks, unable to speak, but bursting with pride. This is what all that sacrifice was for.

Later, over a lavish lunch, Cepricoff reveals that Yelanek's intelligence has been used at the highest level. Not only is it helping stamp out dissident activity, but it has given us a useful bargaining chip with the British and Americans. How so? The Refusnik organisations have many influential friends

in US and British politics. Their lobbying is so successful that their politicians are willing to scale back weapon production in return for the release of high-profile refusnik prisoners. It's no lie to say your work has kept us all safer. Chepprikov stands holding a crystal glass tumbler of plum brandy. The others at the lunch table follow suit. A toast to Comrade Yelanik.

Yelanik basks in the warm glow of praise and attention. After the Soviet delegation leaves, he even feels emboldened to ask his Czech spymaster a question that has been on his mind for some time. When will my posting in England finish? It's been 11 years now. I'd like to settle down and start a family. His boss raises a disbelieving eyebrow. Come home. Don't be ridiculous.

Didn't you hear, Comrade Chebrichoff? You're far too valuable to us over there now. Yelanik feels his warm glow evaporate. First, he wasn't doing well enough. Now he's paying a price for doing too well. A few weeks later, Hampstead Heath, North London. Two MI5 surveillance officers park their car in a residential street with a clear view of the old Bull and Bush pub.

Using small binoculars, one of the MI5 officers watches their target. He's a Soviet diplomat, but after watching him for several months, MI5 is now convinced he's actually an undercover Russian intelligence officer. Their target circles the pub car park perimeter, then leans casually against a brick wall to smoke a cigarette. He's definitely up to something. After a few minutes, the Soviet diplomat abandons his wall pose and enters the pub. The MI5 officers watch and wait.

30 minutes later, a slim, good-looking man in a pinstriped suit drives into the car park. But instead of entering the pub, he also wanders around outside. He stops near the brick wall the Soviet leaned against and appears to search for something. The MI5 officer watches him frowning. Seems like he's someone we should know. Yes, but he's not on the Soviet watch list. Could be an agent. Maybe.

After a few minutes of searching, the mystery man also enters the pub. Charlie 9 to base? Go ahead, Charlie 9. We have an unknown male, mid-30s, well-dressed. We believe he is linked to our... our target. Please advise. Receive Charlie Nine. Follow the unknown. We need a home address and car registration number. Message received. An hour later, the surveillance officers watched the Pinsright man come out of the pub and get into his car. They tail his car through the leafy streets

of Hampstead and north into the suburban streets of Friand Barnett. Finally, the suspected spy. parks in Silver Birch close. As his colleague takes photos, the MI5 officer peers through his binoculars and watches the man enter a small block of new build departments. Number 35. His companion makes a note of the address and car registration. Then they head back to MI5 headquarters. Now they need to find out.
