Day 26 of 90 | 64 days remaining
Theo’s grandmother lived in a small town in Ohio called Millersburg, population 3,200, give or take a few cows. The house was a white colonial with blue shutters and a porch swing that creaked in the wind. His mother had grown up there. Theo had visited every summer until he was twelve, when his mom started working weekends and the trips became less frequent.
Now he was living there. For real. His boxes were stacked in the guest room, the one with the floral wallpaper and the quilt his great-grandmother had made. He’d been there for a week, and he still woke up every morning confused by the ceiling.
This morning, he woke up early. Earlier than usual. The sun hadn’t fully risen; the sky outside his window was a pale, watery gray. He lay in bed for a moment, listening to the house settle. Then he reached for his backpack, pulled out the hardware wallet and the napkin, and carried them downstairs.
Grandma Margaret was already in the kitchen.
She sat at the table with a cup of tea and the local newspaper, reading glasses perched on her nose. She was sixty-eight, with silver hair cut short and practical, and a face that had weathered grief more than once. Her husband—Theo’s grandfather—had died ten years ago. Her daughter—Theo’s mother—had died twenty-five days ago. She didn’t cry in front of Theo, but he’d heard her at night, through the wall, muffled sounds that broke his heart.
“You’re up early,” she said without looking up. “Couldn’t sleep?”
“Something like that.” He sat down across from her. The hardware wallet was in his left hand, hidden under the table. “Grandma, I need to tell you something.”
She set down her newspaper. Folded her reading glasses. Gave him her full attention—the way she always did, the way that made you feel like you were the only person in the world. “I’m listening.”
He placed the hardware wallet on the table.
She looked at it. Then at him. “Is that a computer thing?”
“It’s a crypto wallet. For bitcoin.” He swallowed. “Mom left it for me. It has a lot of money in it.”
Grandma Margaret picked up the device, turned it over in her hands. She didn’t seem impressed or alarmed—just curious. “How much is a lot?”
“About a hundred and forty-seven million dollars.”
The kitchen went very quiet. Somewhere outside, a bird started singing.
Grandma Margaret set the device down carefully, as if it might explode. She took off her glasses entirely and rubbed her eyes. “Theodore James,” she said—she only used his full name when she was serious—“are you telling me your mother had a hundred and forty-seven million dollars in a… a computer stick?”
“A hardware wallet. Yes.”
“And she never told me?”
“She never told anyone. That’s the point.” Theo pulled out the napkin and unfolded it. “She set up something called a multi-sig. She spread the key across five people. Guardians. She needed three of them to agree before I could unlock the money. And one of those guardians, Grandma, is you.”
The silence stretched. The bird outside kept singing.
Then Grandma Margaret laughed. It was a short, surprised laugh—the kind that escapes when your brain can’t keep up with reality. “Me? I don’t know anything about bitcoin. I can barely use my email.”
“That doesn’t matter. Mom gave you something three years ago. A piece of paper. She asked you to keep it safe. Do you remember?”
Grandma Margaret’s face changed. The laughter faded, replaced by something slower, heavier. Memory.
“Three years ago,” she murmured. “She came to visit. Alone. She seemed… scared. I asked her what was wrong, and she said, ‘Nothing, Mom. Just want you to hold onto something for me. Don’t ask why. Just keep it safe.’”
“What did she give you?”
Grandma Margaret stood up slowly, her joints creaking, and walked to the corner of the kitchen. There was a small painting on the wall—a watercolor of Millersburg’s main street, painted by Theo’s grandfather. She lifted it off the hook. Behind it was a small hole in the drywall, and inside the hole, a fireproof safe no bigger than a shoebox.
“She made me promise not to put it in a bank,” Grandma Margaret said as she dialed the combination. “She said banks can be frozen. She said this was safer.”
The safe opened with a soft click. Inside: a few folded documents, a savings bond from Theo’s birth, and a laminated card.
She handed the card to Theo.
It was the size of an index card, covered in plastic laminate. On it, printed in small, precise letters, was a string of characters sixty-four digits long. Letters and numbers, upper and lowercase, symbols mixed in. It looked like nonsense.
At the bottom, in his mother’s handwriting: For Theo. When he’s ready.
“That’s the shard,” Theo whispered. “That’s one of the five.”
He called Zara immediately. Put her on speaker so Grandma Margaret could hear.
“You have the shard?” Zara’s voice crackled through the phone.
“My grandma had it. Hidden behind a painting.”
“Good. Don’t lose it. Don’t photograph it. Don’t type it into any online form. Ever. That shard is useless alone, but if someone gets it and also gets two others, they could reconstruct the master seed. So treat it like a nuclear launch code.”
Grandma Margaret raised an eyebrow. “Nuclear?”
“Figuratively, ma’am. Mostly.” Zara cleared her throat. “Theo, I need you to verify the shard against the public wallet. Do you have the hardware wallet with you?”
“Right here.”
“Plug it in. Go to the recovery menu. There should be an option to ‘test shard fragment.’ Do not click ‘combine’ or ‘reconstruct.’ Just ‘test.’”
Theo plugged the hardware wallet into his laptop. The black-and-green screen appeared. He navigated to the recovery menu—it took three tries, because the button was finicky—and found the option Zara had described.
“Okay,” he said. “It’s asking for the shard.”
“Type it in. Slowly. Double-check every character.”
He typed. It took four minutes. His fingers were shaking. Grandma Margaret stood behind him, one hand on his shoulder.
He pressed ENTER.
The screen flickered. Then a message appeared:
SHARD VALID. GUARDIAN 1/5 CONFIRMED. THRESHOLD NOT MET.
Theo let out a breath he didn’t know he’d been holding. “It worked. It’s valid.”
On the phone, Zara exhaled too. “One down. Four to go. But remember—we only need three total. So technically, we need two more willing guardians.”
Grandma Margaret squeezed his shoulder. “I don’t understand half of what just happened,” she said. “But I understood your mother. If she wanted me to help you, I help you. Whatever that means.”
“It means you’re Guardian Number One,” Theo said. “Thank you, Grandma.”
“Don’t thank me yet. We’ve got four more to find.”
Zara had already identified the second guardian. Her name was Elena Vasquez, and she lived in Austin, Texas. She had been Theo’s mother’s business partner in a sustainable farming startup that never quite took off. Theo remembered Elena vaguely—tall, with long black hair and a laugh that filled a room. She’d come to his eighth birthday party and brought a piñata shaped like a planet.
That was six years ago. They’d lost touch after the startup failed. His mother never talked about why.
Now, sitting at Grandma Margaret’s kitchen table, Theo dialed Elena’s number. Zara was on a separate video call, muted, watching. Grandma Margaret sat across from him, holding his free hand.
The phone rang three times. Then: “Hello?”
Elena’s voice was older now. Rougher. But still recognizable.
“Elena? It’s Theo. Theo Matsumoto. My mom was—”
“Claire.” Elena’s voice cracked. “I know who you are, Theo. I saw the obituary. I’m so, so sorry. I should have called. I should have—I just didn’t know what to say.”
“It’s okay,” Theo said, even though it wasn’t. “I’m calling because Mom left me something. A crypto wallet. And she named you as one of the guardians.”
A long pause. He could hear Elena breathing.
“I remember,” she said finally. “Three years ago. She came to Austin. She looked… I’d never seen her like that. Serious. Frightened. She gave me a card with a long string of numbers and letters. Told me to keep it safe. Said it might matter someday.” Another pause. “I thought she was being dramatic. Your mother was always a little dramatic.”
“She wasn’t being dramatic,” Theo said. “There’s a lot of money in that wallet. And there’s a man—a wallet hunter—trying to take it. I need your help. I need your shard.”
“My shard.” Elena laughed, but there was no humor in it. “Theo, I loved your mother. I did. But crypto brings out the worst in people. How do I know this isn’t a scam? How do I know you’re really you?”
Zara unmuted herself. “Because I’m a licensed recovery specialist, Ms. Vasquez. My name is Zara Chen. I’m on the line with Theo and his grandmother. We can provide documentation. We can set up a secure video verification. And most importantly—you don’t have to give anyone your shard. You just have to participate in a threshold ceremony where your shard is combined with two others in a way that no single person sees the full combination.”
“And who are you?” Elena asked. “A sixteen-year-old girl? According to your LinkedIn.”
“Age isn’t a credential,” Zara said evenly. “But I’ve successfully recovered four orphaned wallets in the past two years. I’ve never lost a client to the Vulture or anyone else. And I’m doing this for Theo pro bono because his mother built a recovery network that actually works.”
Another long silence. Then Elena sighed. “Send me the legal agreement. I’ll have my lawyer look at it. But Theo—I need you to understand something. Your mother and I… we didn’t end well. The startup fell apart. I blamed her. She blamed me. We stopped talking. And now she’s gone, and I can’t fix that. But I can help you. So I will. On one condition.”
“What condition?”
“I want proof that every other guardian is willing and not coerced. I won’t be part of something where people are being pressured. No threats. No manipulation. That’s what your mother would have wanted.”
Theo looked at Zara’s face on the laptop screen. She looked annoyed—her jaw was tight, her eyes narrow. But she nodded.
“That’s fair,” Theo said. “I promise. No pressure. No manipulation. Just people choosing to help.”
“Then send me the paperwork,” Elena said. “And Theo?”
“Yeah?”
“Your mother was proud of you. I know she was. She talked about you all the time. You were the best thing in her life.”
Theo’s throat closed up. He managed a small “thank you” before Elena hung up.
That night, Theo couldn’t sleep.
He lay in the guest room, staring at the ceiling, running through the math in his head. Two guardians down. Three to go. They only needed one more willing signer to reach the threshold—three total. But the remaining guardians were unknown quantities.
Zara had sent him the preliminary profiles before she logged off.
Guardian Three: Marcus Webb, 55, reclusive coder, rural Montana. Last confirmed online activity: 8 months ago. No social media. No listed phone number. Zara was trying to find a way to contact him.
Guardian Four: Dr. Priya Sharma, 47, dermatologist, Chicago. Former best friend of Claire Matsumoto. Friendship ended five years ago for unknown reasons. Contact information available.
Guardian Five: [REDACTED]. Identity sealed in a legal trust. Requires court order or biometric confirmation. Status unknown. Possibly deceased.
“Two for sure,” Theo whispered into the dark. “Two willing. That’s not enough.”
He thought about his mother, sitting in this very house three years ago, handing her mother a laminated card. Don’t ask why. Just keep it safe. She had been planning for this. She had known, maybe, that she wouldn’t be around forever. She had built a system—a circle of trust—to make sure Theo would be okay.
But she hadn’t counted on Marcus disappearing. Or Priya’s anger. Or Guardian Five vanishing into a legal black hole.
What would you do, Mom?
The answer came to him slowly, the way answers do in the quiet hour before sleep. She would keep going. She would find a way. Because that’s what she had always taught him: You don’t stop when it gets hard. You stop when it’s done.
He reached for his phone and sent Zara a message.
Theo: Who’s next? Marcus or Priya?
Her reply came within seconds. Zara never seemed to sleep.
Zara: Marcus is a ghost. I’ll keep digging. Priya we can call tomorrow. But fair warning—she’s going to want something in return. People like her always do.
Theo: Then we find out what it is.
Zara: And if it’s something you can’t give?
Theo stared at the screen. Outside, an owl hooted. The house groaned.
Theo: Then we find another way.
He put the phone down and closed his eyes. In his mind, he saw the map Zara had shown him—five pulsing dots. Two were green now. Grandma Margaret. Elena Vasquez.
Three were still gray.
Tomorrow, he would start turning them green.
