Rain hammered the streets of Geneva like bullets from the sky.
Inside a quiet apartment overlooking the lake, Agent Marcus Hale sat at his desk, staring at the glowing screen of his laptop. Lines of encrypted code scrolled endlessly across it. Normally, the sight would calm him.
Tonight, it didn't.
Something was wrong.
Marcus had worked for Aegis International Security for twenty years. Long enough to know when the world was about to explode. His instincts had saved his life dozens of times.
And right now, those instincts were screaming.
On the screen flashed a message he had never expected to see.
SHADOW PROTOCOL ACCESS NODE COMPROMISED
Marcus felt his stomach drop.
"That's impossible," he muttered.
The Shadow Protocol was the most secret system ever created. A hidden network controlling surveillance satellites, military drones, and intelligence feeds from nearly every country on Earth.
Only five agents had access to its master keys.
Marcus was one of them.
If the system had been compromised, it meant one thing.
Someone was hunting the keyholders.
Marcus reached for the secure phone on his desk and dialed the first number.
The call never connected.
Instead, the lights in the apartment flickered once.
Then went dark.
Marcus froze.
His hand slowly moved toward the pistol hidden in the drawer.
The silence was terrifying.
Then—
CRASH!
The balcony glass exploded inward.
A black-clad figure rolled across the floor, landing perfectly on their feet. Another followed. And another.
Three assassins.
Marcus pulled the pistol and fired twice.
BANG! BANG!
One attacker dropped instantly, blood spreading across the floor.
But the other two moved like shadows.
A flash of metal cut through the darkness.
Marcus barely dodged the blade slicing toward his throat. He slammed the desk forward, knocking one assassin into the wall.
But the third one raised a suppressed pistol.
Pfft.
Marcus felt the bullet punch into his shoulder. He staggered backward.
The assassin stepped closer.
No words. No hesitation.
Professionals.
Marcus coughed, gripping the desk for support. Blood soaked through his shirt.
"You're too late," he said with a weak smile.
The assassin tilted their head slightly.
Marcus reached the laptop and slammed one final key.
Across the world, hidden servers activated.
A message shot through the encrypted Aegis network.
SHADOW PROTOCOL TRANSFER INITIATED
The assassin realized too late.
"Stop him!" one of them shouted.
But Marcus had already hit ENTER.
Thousands of kilometers away, in a quiet training facility…
A teenager's phone buzzed.
The assassin pulled the trigger again.
Pfft.
Marcus Hale collapsed beside his desk.
The laptop screen flashed once before going black.
TRANSFER COMPLETE
Across the world, in a dim dorm room filled with training gear and old action posters, 17-year-old trainee agent Adrian Cross blinked at his phone.
A message had appeared from a classified system he wasn't supposed to access.
He rubbed his eyes.
"Did someone send this by mistake?"
The message contained only four words.
YOU ARE THE LAST KEY
Adrian frowned.
"What does that even mean?"
Outside his window, the wind howled through the trees.
Far away, in multiple countries, four other keyholders of Shadow Protocol were already dead.
And now…
Every intelligence agency, mercenary group, and assassin network in the world would soon discover one thing.
The final key to Shadow Protocol now belonged to a teenager who had no idea what he had just inherited.
And the hunt was about to begin. 🔥📖
