The envelope shouldn’t have existed.
It lay on Emma Taylor’s kitchen table, yellowed at the edges, her name written across the front in a looping, familiar script that had carved itself into her memory years ago.
Dr. Emma Taylor.
Her father’s handwriting.
Except Dr. John Taylor had been dead for thirteen months.
Rain tapped a restless rhythm against the apartment windows, matching the uneven thud of her heart. Emma sat motionless for a moment, fingers hovering just above the paper. She didn’t remember this envelope from the boxes of his things the university had sent. She’d found it only that morning, wedged between two dusty journals at the bottom of a crate she’d been avoiding since the funeral.
“Stop staring and open it,” she muttered to herself.
Her hands shook as she slid a thumb under the seal. The paper tore with a soft, final sound. Inside, there was only one sheet no equations, no diagrams, no data like the hundreds of documents she’d inherited from him. Just his careful handwriting, neat and steady, as if he’d known she would be trembling when she read it.
My dearest Emma,
If you are reading this, it means I am no longer there to explain things in person. I hate that. I always imagined we would argue about my decisions face-to-face, over coffee you complain is too weak.
My death will not be an accident. Remember that.
I have uncovered something dangerous so dangerous that I cannot trust it to any institution, any company, any government. If the wrong people control it, the world will suffer for it.
I need you to do what I should have done sooner. Take what you find in my lab to the authorities. Do not try to handle this alone. Some of the people involved will stop at nothing to keep this buried.
I wish I had more time to prepare you. But I know you, Emma. Your mind, your stubbornness, your heart. You are the only person I trust to make the right choice.
Whatever happens, remember: you were never my second choice. You were always my legacy.
I love you more than anything.
Forever your father,
Dr. John Taylor
Emma’s vision blurred. She blinked hard, refusing to let the tears fall. She read the last line again. You were always my legacy.
For a year she had tried to accept the official story: a mugging gone wrong, a late-night walk home from the lab, no witnesses. Clean. Simple. Random.
Her father’s letter burned through that lie in a handful of sentences.
“My death will not be an accident.”
Her stomach twisted. For months, grief had wrapped itself around her like a heavy blanket smothering, dull, bleak. Now something sharper pushed through it: anger. Someone had killed her father. Not fate, not bad timing, not a nameless street thug.
And they were still out there.
Emma folded the letter carefully, as if it might c***k if she rushed, and slipped it back into the envelope. Her gaze drifted to the framed photo on the counter: her and her father in the lab, both in oversized goggles, laughing at something off-camera. He’d always said science was just structured curiosity. Right now, curiosity felt like gasoline poured over grief.
He left you a trail, she told herself. Start there.
The university lab hadn’t changed.
The building’s glass doors sighed open with the same mechanical hiss. The hallways still smelled faintly of disinfectant and burnt coffee. Students in white coats moved past her, a blur of voices and footsteps; no one looked twice at her ID badge. Once, she had felt at home here. Now the corridors felt like a museum exhibit of a life that had been cut off mid-sentence.
Her father’s office was at the end of the hall, the frosted glass pane still bearing his name.
Dr. John Taylor - Energy Systems Research
No one had scraped it off yet. The sight tightened her throat.
Emma unlocked the door with the key she still carried on her ring. The office greeted her with dust and silence. Stacks of journals and papers were neatly arranged on the shelves, as if he had just stepped out for a meeting and might return any minute, cursing about a delayed experiment.
She shut the door behind her and leaned against it for a moment, letting the memories rise and fall without drowning her: his voice explaining quantum efficiencies, his laughter when she’d spilled reagents on her first day as his intern, the way his eyes would light up when an idea clicked.
“All right, Dad,” she whispered. “What were you doing that got you killed?”
She started with the obvious: desk drawers, filing cabinets, the safe behind the framed certificate. Most of what she found was boring grant proposals, experiment logs, decades of neatly labeled data. Money for this. Approval for that. Nothing that screamed lethal secret.
Then she saw it.
A plain black binder tucked sideways at the back of a shelf, spine unmarked. No title. No label. Just a small, handwritten X on the lower corner.
She pulled it free. A thin layer of dust puffed into the air.
Inside, the first page held only two words:
PROJECT X - HELIOS PROTOCOL
Her pulse spiked. She flipped to the next page. Equations swarmed across it, dense and elegant, the kind only her father wrote complex yet oddly clean, as if the math itself trusted him.
Energy yield projections. Solar capture arrays. Conversion efficiency rates that made her breath catch in her chest.
“This can’t be right,” she murmured.
If his calculations were even close to accurate, Helios wasn’t just an incremental improvement. It was a revolution an almost-lossless method of harnessing the sun’s energy, scalable, modular, and clean. The kind of breakthrough that would make fossil fuels obsolete. The kind of technology entire industries would kill to control or to bury.
Emma turned another page. The tone shifted. No more neat equations. Instead: short, frantic notes.
Meeting with board today. Not comfortable. Someone else in the room who shouldn’t be.
Offer from private investor. Terms too good. Motives unclear.
Phone call. Voice disguised? Said “Let the sun set, Doctor.” Threat? Paranoia?
Her fingers dug into the paper as she turned to the final pages. The handwriting had grown uneven, the lines slanting downward as if he’d written them in haste.
Second warning delivered. This time in person. They know where Emma lives.
Must leave a trail. In case they do more than threaten.
A date was scribbled beneath the last entry. Two days before he died.
The room blurred, then snapped back into focus.
They knew where she lived.
They had threatened her.
“This is why you pushed me to move out of the city,” she whispered, remembering his insistence, the strange urgency behind it. “It wasn’t about ‘growing up,’ was it?”
He’d been trying to move her out of the line of fire.
Emma closed the binder and hugged it to her chest for a second, grounding herself in the solid weight of it. Then she crossed to the office copier. It whirred to life, light sweeping back and forth as she copied every page of Project X Helios Protocol. She slipped the original binder back exactly where she’d found it.
If someone came looking, she didn’t want them to know she’d been here.
The copies went into her bag, along with the envelope and letter. Her father’s words echoed in her mind.
Take what you find in my lab to the authorities.
Do not try to handle this alone.
She hated that part. Alone was how she had survived the last year. Alone made sense. Alone didn’t get other people killed.
But she’d promised herself she would honor his last request even if she didn’t like it.
Detroit’s central police station looked more like a weary office building than a fortress of justice. The fluorescent lights hummed overhead as Emma stepped inside, the smell of burnt coffee and printer toner hitting her in a familiar wave. She clutched her bag strap, feeling suddenly underdressed in her jeans and raincoat, like she should’ve worn armor instead.
The officer at the front desk glanced up. “Can I help you?”
“I need to speak to a detective,” Emma said. “It’s about a murder.”
That word still scraped against her throat.
After a few minutes and a phone call, she was led down a hallway into a small interview room that tried and failed to feel welcoming. Metal table. Two chairs. A camera in the corner pretending not to stare.
The man who walked in a moment later looked exactly how she imagined a detective shouldn’t want to look if he hoped to be underestimated: tall, broad-shouldered, gray at the temples, jaw set in a way that said he’d seen too much and cared anyway.
He dropped a file onto the table and sat. “Dr. Emma Taylor?” His voice was low, steady.
“Yes.” She straightened.
“I’m Detective Ryan Cole.” He opened the file. Her eyes caught the header: Taylor, John - Homicide Investigation (Closed). “I worked your father’s case.”
Something tightened in her chest. “You closed it as a mugging.”
He met her gaze without flinching. “Because that’s what it looked like. No witnesses. No missing items beyond his wallet and watch. No signs of premeditation.”
“He left me a letter,” Emma said, cutting him off. Subtle wasn’t in her vocabulary anymore. “He says his death would not be an accident. That he’d uncovered something dangerous. That people had threatened him. He was working on a project Helios. A way to harness solar energy on a scale that would make entire industries obsolete.”
She set the copies of Project X on the table, along with the envelope. The sound echoed in the small room.
For a moment, Detective Cole just watched her, weighing her, measuring the edges of her desperation. Then he picked up the letter. His eyes moved silently across the page. Something in his expression shifted barely, but enough.
“This is his handwriting?” he asked.
“Yes.”
“And you found this where?”
“In his old lab. Along with those notes.” She nodded at the Helios file. “They threatened him, Detective. He wrote that they knew where I lived.”
He sat back slowly, flipping through the copies of the project. The equations probably meant nothing to him, but the word threats didn’t need translation.
“When was the last time you saw anyone watching you, following you, anything like that?” he asked.
Emma hesitated. She thought of the dark car she’d noticed once, parked across from her building too late at night. Of the feeling of being observed as she walked to the bus alone, the prickle on the back of her neck she’d chalked up to grief and paranoia.
“I don’t know,” she admitted. “I thought it was just in my head. I didn’t know there was a reason to be afraid.”
Cole nodded slowly, as if that matched a story he’d heard a hundred times in a hundred different forms.
“All right,” he said. The no-nonsense in his tone softened by a fraction. “Here’s what we’ll do. I’ll reopen your father’s case on the record. Officially, that’s a paperwork nightmare. Unofficially…” A hint of steel slid into his eyes. “I should have pushed harder back then. If there’s more to this, I’ll find it.”
“You’ll actually look into it?” The hope in her voice annoyed her; she didn’t want to sound like she needed saving.
He met her gaze head-on. “You brought me a letter from a murder victim predicting his own death, plus records of threats and a game-changing energy project. I’d have to be an i***t to ignore that.”
For the first time since opening the envelope, Emma felt something that wasn’t grief or rage. It wasn’t quite relief, either. More like a shift. As if a heavy door she hadn’t known existed had opened a c***k.
“Good,” she said. “Because I’m not going to ignore it either.”
A faint, reluctant smile ghosted across his face. “I figured.”
He slid a card toward her. “You call me if you see anything strange. Anyone following you. Any new messages, letters, emails. Don’t confront anyone yourself. You’re smart. Stay alive, too.”
Emma picked up the card, feeling the edges press into her palm. “I’m not reckless,” she said.
He raised an eyebrow at the stack of stolen research notes between them. “We’ll see.”
By the time she stepped back out onto the street, the rain had slowed to a drizzle. The city buzzed around her—car horns, distant sirens, the murmur of people with simpler problems.
She pulled her coat tighter and started toward the bus stop, replaying the day in her mind. The envelope. The letter. Helios. Detective Cole’s eyes hardening as he read her father’s words.
My death will not be an accident.
As she waited at the corner, a car rolled past. Dark sedan. Tinted windows. Nothing illegal. Nothing obvious.
Still, the hairs on the back of her neck rose.
The car slowed for just a heartbeat as it passed her, then continued on.
Emma watched it disappear into the traffic, her heart thudding.
Maybe it was random.
Maybe it wasn’t.
Either way, one thing was suddenly, painfully clear:
Her father had died for something he believed could change the world.
And now, whether she was ready or not, Emma Taylor was stepping into the same shadow that had swallowed him.
The discovery of death had already rewritten her life.
She had no idea yet that it was also leading her slowly, dangerously toward the discovery of love.
