Every morning I woke up nauseous, doctors shrugging and saying, “All your tests are normal.” Then on the subway, a jeweler brushed my hand and whispered, “Take off that necklace—now.” He pointed at the pendant and my stomach dropped. When I confronted my husband, he went pale and said, “You weren’t supposed to find out.” That was the moment I realized my sickness wasn’t an accident—and neither was our marriage.

Chapter 1: The Nameless Illness

Three months ago, I started waking up with a metallic taste in my mouth. Not the kind of iron you get when you bite your tongue, but a bitter, cold taste, as if I’d been holding a handful of old coins in my mouth all night.

Then came the nausea.

“It’s just stress, Sarah,” Dr. Evans said, glancing through my medical records at the expensive private clinic on the Upper East Side. “Blood tests, urine tests, MRI… all your indicators are normal. Even perfect. Maybe you should see a psychologist? At 32, work and marriage stress can cause psychosomatic symptoms.”

I walked out of the clinic feeling like a madwoman. My husband, Mark, met me in the lobby. He’s a risk assessor for a large insurance corporation. Handsome, considerate, and always rational.

“They said I was fine again?” Mark asked, gently draping his cloak over my shoulders.

“Yes,” I sighed, my hand unconsciously touching the pendant around my neck. “I don’t know what’s wrong with me.”

“You just need to rest,” Mark kissed my forehead. “And don’t take that necklace off. It suits you so well. It protects you.”

The necklace. It was a gift from Mark to celebrate our fifth wedding anniversary. An exquisite platinum chain with a pendant that was a shiny, dark gray metal block encased in a silver mesh frame. Mark said it was rare hematite (black quartz), mined from meteorites, capable of balancing energy.

I loved it. I wore it 24/7. Even in the shower, because Mark said the water would make the stone shine brighter.

But my health was deteriorating. My hair was starting to fall out in clumps. My skin was turning a pale gray. And then, inexplicable bruises appeared on my chest, right where the pendant had rested.

Chapter 2: The Meeting on the L Train

Today, Mark was away on business. I decided to go to another specialist clinic in Brooklyn by myself for a second opinion. I took the L Train during off-peak hours.

The train car was deserted. I sat huddled in the corner, trying to suppress the rising nausea. Opposite me was an elderly man with a long, gray beard, wearing a worn-out woolen coat. He wore a jeweler’s magnifying glass around his neck and was intently examining a gold ring.

The train shook. My pendant slipped out of my sweater collar, dangling in front of my chest.

The old man looked up. His eyes met the pendant.

Suddenly, his pupils contracted. He sprang to his feet, staggering toward me as if hypnotized or terrified.

“Sir?” I recoiled, frightened.

He didn’t answer. He lunged forward, gripping my wrist with his rough, cold hand.

“Take that necklace off immediately,” he whispered, his voice hoarse, distinctly Eastern European.

“Let go of me! What are you doing?” I screamed, trying to pull my hand away.

“You wouldn’t understand!” he hissed, pointing with a trembling finger at the dark gray pendant. “I’ve been a jeweler for 40 years on Diamond Street. I know gemstones. And I know what fakes are.”

He stared into my eyes, the fear in them so real it sent chills down my spine.

“That’s not Hematite. And it’s not a meteorite. Look at your skin, girl. Look at your hair. You’re dying.”

“What the hell are you talking about?”

“That pendant,” he lowered his voice to the absolute minimum, as if afraid someone might hear. “It’s ‘hot.’ Not temperature. It’s radiation.”

I was speechless. “Radiation?”

“I saw something similar on the black market in the ’90s,” he said quickly, his eyes scanning the train car. “It’s Cobalt-60. Or maybe Caesium-137. It’s scrap from old medical or industrial equipment, polished and sold to stupid or evil people. If you wear it every day… it’s destroying your cells from the inside. Take it off! Throw it away! Right now!”

Just then, the train stopped at Bedford Avenue station. The doors opened.

The old man looked at me one last time, thrusting a crumpled business card into my hand. “If you want to live, come see me. But get rid of that damned thing first.”

Then he dashed off into the crowd, leaving me sitting there, my heart pounding, my hand clutching the pendant that was emitting a strange warmth – something I had always thought was “healing energy.”

Chapter 3: The Geiger Counter

I didn’t throw it away. I needed proof.

I got off the train, took a taxi to a safety equipment store. I bought a cheap handheld radiation meter (Geiger counter).

I arrived back at our penthouse apartment in Tribeca. Mark wasn’t home yet.

I placed the pendant on the kitchen counter. I turned on the meter, bringing the probe close.

Click… Click… Click…

The machine beeped slowly. It was a normal background radiation level.

I brought the probe closer, touching the pendant.

CLICK CLICK CLICK CLICK CLICK CLICK!!!

The machine beeped frantically, the needle darting to the red zone, all the way to the bottom. The electronic screen flashed the word DANGER.

I dropped the device to the floor.

The old man was right. I was wearing a miniature nuclear reactor around my neck. A slow-fire radioactive bullet.

And

Mark… Mark gave it to me. Mark told me never to take it off. Mark said it would “protect” me.

The front door swung open. Mark walked in, pulling his suitcase, a radiant smile on his face.

“I’m home earlier than expected!” Mark called out. “Sarah? Where are you?”

I stood in the kitchen, staring at the necklace on the table. I hadn’t had time to hide it.

Mark walked into the kitchen. He saw me. Then he saw the radiation meter lying on the floor, still beeping miserably. And the necklace lying alone on the table.

Mark’s smile vanished. His handsome face hardened, becoming distant and cold.

“Sarah,” he said, his voice low. “What are you doing?”

“It’s radiation,” I whispered, tears welling up. “You gave me a piece of radiation. You’re killing me.”

Mark didn’t deny it. He didn’t panic either. He just sighed, untied his tie, and draped it over the chair. He was frighteningly calm.

“You shouldn’t know this,” Mark said. “You should have just gradually weakened and passed away peacefully from ‘acute leukemia.’ Like your mother.”

I recoiled, bumping into the refrigerator. My mother had died of leukemia last year.

“You… you killed my mother too?”

“No, she died naturally. But her death gave me a brilliant idea,” Mark moved closer, step by step. “Your family has a genetic history of cancer. If you died of bone marrow failure or blood cancer, no one would suspect anything. The doctors would just shrug and say ‘hereditary.'”

“Why?” I yelled. “We’re happy! I love you!”

“Happy?” Mark scoffed. “Sarah, you’re a music teacher. You earn $50,000 a year. I’m a risk assessor. I see the numbers. And the biggest number I see is the $5 million life insurance policy I bought you two years ago, plus this house in your name.”

“You’re in debt,” I realized. “You lost at gambling, didn’t you? Those business trips…”

“Yes. I owe money to people who don’t know how to joke. And your life is my ticket out of debt.”

He looked at the necklace.

“I got that Cobalt-60 from an old radiotherapy machine in Mexico. It’s hard to find. I wrapped it carefully, leaving only one side exposed to your skin. It kills slowly, silently, leaving no trace of poison. But you’re too curious.”

Mark pulled a pair of leather gloves from his pocket. He put them on.

“Now I have to do it in a more chaotic way. I’ll force you to swallow that ice. Then I’ll throw your body into the Hudson River. The police will think you committed suicide from depression.”

Chapter 3: The Predator’s Twist

Mark lunged at me. He was much stronger than me. He grabbed my hair and slammed my head against the refrigerator door. I staggered and fell to the floor.

He snatched the necklace from the table. He pinned me down and forced my mouth open.

“Swallow it! Swallow it now!” he roared, his hand holding the pendant to my mouth.

I struggled, scratching at his face. But my strength had been drained by the radiation sickness of the past three months. I was as weak as a sickly cat.

The ice-cold stone touched my lips. I was about to die.

But in that moment of impending death, my brain suddenly remembered a detail. A small detail that Mark – the self-proclaimed genius of calculation – had overlooked.

This morning, before my doctor’s appointment, I stopped by the bank. I changed the beneficiary of my insurance policy.

But that wasn’t what saved me.

What saved me was… the old man on the subway.

The business card he gave me. I’d stuffed it in my back pocket. It was bulging.

No, not the business card.

When Mark leaned down, his face was close to mine. I saw the madness in his eyes.

I couldn’t defeat him with brute force. I had to use his weapon.

I stopped resisting. Mark thought I’d given up. He loosened his grip slightly to push the stone deeper.

I used all my strength, not to push him away, but to snatch the necklace from his hand.

And I slammed it into his eye.

Not the pendant. But the clasp.

Mark screamed in pain, let go of me, and clutched his left eye.

I scrambled to my feet. I grabbed the Geiger counter from the floor. It was quite heavy.

BAM!

I slammed the device into Mark’s head. He fell face down.

I ran to the door. But it was locked from the inside – a habit Mark had when he came home.

Mark scrambled to his feet, blood streaming from his forehead. He laughed maniacally.

“You can’t get away, Sarah. This apartment is soundproof.”

He lunged again.

I backed into the living room. I saw the utility knife on Mark’s desk. I grabbed it.

But Mark grabbed my leg. He pulled me down.

We wrestled on the floor. He choked me. My vision blurred.

Suddenly, the doorbell rang.

Ding Dong.

Mark froze. He looked to the door. Who could be here at this hour?

“Help me!” I tried to scream, but only a whisper came out.

CRASH!

The thick oak door was flung open with immense force.

A SWAT team stormed in, guns at the ready.

“FBI! TAKE HER OFF! LIE DOWN!”

Mark was kicked away, pinned to the floor. Handcuffs snapped onto his wrists in an instant.

I lay there, gasping for breath, unable to breathe.

I didn’t understand what was happening. Why was the FBI here? I hadn’t even called the police yet!

A man in a suit walked in behind the special forces team. He wore sunglasses and carried a specialized radiation detector (much larger than mine).

He wasn’t the old man from the ship.

He approached me and helped me up.

“Ms. Vance, you’re safe.”

“Who are you?” I asked, my voice trembling.

“We are the FBI’s Nuclear Counterterrorism Unit,” the agent said. “We’ve been tracking your husband, Mark Evans, for six months.”

Chapter Conclusion: The Final Truth

It turned out that Mark wasn’t just an insurance fraudster or a gambler.

Mark was a link in a nuclear materials smuggling ring from South America to the United States. The Cobalt-60 stone around my neck wasn’t a random stone.

That’s The Sample.

Mark needed to transport this radioactive stone across the border and hide it safely before delivering it to the buyer (a domestic terrorist group wanting to build a dirty bomb). But the radiation detectors at airports and seaports were too sensitive. He couldn’t carry it in his luggage.

He came up with the most cruel solution: turning his wife into a carrier.

He wrapped the stone in lead (the silver outer layer was actually a lead-silver alloy to block some radiation, preventing detection by long-range scanners, but still enough to leak and harm the wearer). He wore it around my neck.

When passing through checkpoints, if the alarm went off, he would say it was because I had just undergone cancer radiation therapy (he had falsified my medical records to prove I was being treated for thyroid cancer). Because I looked sickly (caused by the stone itself), security would believe me and let me through.

I was a living mule, unknowingly a human mule.

The FBI had been tracking that faint radioactive signal throughout the city. But they didn’t dare arrest Mark immediately for fear he would detonate the explosives or dispose of other materials.

The old man on the subway? He was actually a retired nuclear physicist who had worked for the government. He noticed the signs of radiation on my skin and reported it to the FBI hotline as soon as he got off the train. His call prompted the FBI to raid the facility sooner than planned.

Mark was sentenced to life imprisonment for smuggling nuclear materials and attempted murder.

I underwent two years of radiation detoxification and a bone marrow transplant. I can no longer have children, but I am alive.

I sold my apartment in Tribeca and moved to a rural area in Vermont.

Every morning when I wake up, I no longer taste the metal in my mouth. I breathe fresh air.

There’s no necklace left around my neck now. I leave the faint scar where the stone once rested exposed, as a reminder:

That the man who says, “You deserve the best,” is sometimes the one preparing the worst for you. And that our intuition – that morning nauseous feeling – is the most reliable early warning system, one that no machine can replace.
