CHAPTER 1 — THE LAST REQUEST
The death chamber at Black Ridge Maximum Security Prison had witnessed many final hours.
Men screamed.
Some prayed.
Others cursed everyone they had ever known.
But Prisoner #77194...
Did none of those things.
Mateo Vargas simply sat in silence beneath the cold white glow of a flickering fluorescent light, listening to the slow drip of water falling somewhere beyond the concrete walls.
Each drop sounded like another second disappearing forever.
Outside his tiny cell, armed soldiers changed shifts with military precision.
The execution order had already been signed.
At exactly six o'clock the following morning, Mateo would be led through the final corridor and executed under military authority for the murder of Captain Alejandro Ruiz during one of the bloodiest anti-cartel operations in northern Mexico.
There would be no appeal.
No governor's pardon.
No miracle.
The newspapers had already written his obituary.
To the nation...
He was a traitor.
To the police department...
He was the officer who sold his soul to the cartel.
To his own family...
He no longer existed.
But only Mateo knew the truth.
And if he died...
That truth would die with him.
A prison guard slid open the small metal hatch.
"You've been offered a final meal."
Mateo never looked up.
"I'm not hungry."
"You may request a priest."
"No."
The guard frowned.
"You can call your family."
A long silence followed.
Finally Mateo whispered,
"They buried me three years ago."
The guard stood there awkwardly before asking the question required by prison protocol.
"Is there anything else?"
For the first time all night...
Mateo lifted his eyes.
They were tired.
Bloodshot.
Yet strangely calm.
"Yes."
The guard grabbed his clipboard.
"What is it?"
"I want to see Sombra."
The pencil stopped moving.
"The dog."
"My partner."
"My brother."
The guard blinked.
"You mean...your old K9?"
Mateo nodded once.
"One last time."
The request spread through the prison faster than wildfire.
Inside the officers' cafeteria, guards laughed.
"The murderer wants his dog."
"What does he think this is? A movie?"
Another officer shook his head.
"That dog belongs to Deputy Commander Héctor now."
"He'd never agree."
But not everyone laughed.
Older officers who had once worked narcotics exchanged uneasy glances.
They remembered Sombra.
The Belgian Malinois with the impossible record.
Over two hundred successful drug seizures.
Thirty-seven hostage rescues.
Four officers pulled alive from collapsed buildings after explosions.
And one legendary incident where Sombra detected an explosive device hidden beneath a police convoy almost fifteen minutes before detonation.
The department had called him...
The Ghost Nose.
Because Sombra almost never made mistakes.
Almost.
Captain Ruiz used to joke,
"If Sombra ever accuses you...
Confess."
Back then...
Mateo and Sombra were inseparable.
The dog slept beside Mateo's locker.
Rode in the passenger seat of his patrol truck.
Even waited outside the bathroom during long shifts.
Officers often joked that Sombra obeyed Mateo better than most rookies obeyed their commanders.
Then came Operation Black Canyon.
The mission that changed everything.
Officially...
Captain Ruiz received intelligence that a cartel safehouse near Tijuana contained millions in cash, military-grade weapons, and the leaders of an international trafficking network.
The strike team entered before sunrise.
Thirty-one officers.
Six armored vehicles.
Two K9 units.
Only twenty-seven officers came back.
Captain Ruiz died from three bullets fired at close range.
According to the investigation...
Only Mateo's service weapon matched the fatal rounds.
His fingerprints were everywhere.
Witnesses claimed they saw him arguing with the captain minutes before the shooting.
The most devastating testimony came from one man.
Deputy Commander Héctor Alvarez.
Mateo's own brother-in-law.
Standing in military court, Héctor looked directly into the judges' eyes.
"I watched Mateo execute Captain Ruiz after revealing his loyalty to the cartel."
The courtroom gasped.
Mateo's wife, Isabel...
Collapsed into tears before the verdict was even announced.
Three days later...
She filed for divorce.
One week later...
She changed the children's last name.
Two months later...
She refused every request for visitation.
Even the birthday cards Mateo mailed from prison came back unopened.
Only one thing haunted him more than losing his family.
Sombra.
No one ever allowed him to know what had happened to the dog after his arrest.
Some officers claimed Sombra had retired.
Others said he had been reassigned.
A few whispered the dog had become Héctor's personal K9.
That rumor hurt the most.
Because Mateo knew something nobody else understood.
Dogs don't choose new partners.
Not like that.
Not after eight years.
Not after surviving bullets together.
Near midnight...
The prison warden finally arrived.
He unlocked the cell personally.
Behind him stood four heavily armed military officers and the prison psychologist.
The atmosphere felt strangely tense.
"Vargas."
Mateo stood without resistance.
"Your request has been approved."
For the first time in years...
A tiny spark appeared in Mateo's eyes.
The warden continued carefully.
"You'll have exactly ten minutes."
"No physical aggression."
"No attempts to escape."
"No unnecessary conversation."
Mateo simply nodded.
As they fastened heavy chains around his wrists and ankles...
The prison psychologist quietly asked,
"Why your dog?"
Mateo smiled for the first time in nearly three years.
It wasn't a happy smile.
It was the smile of someone remembering the last honest friend he had ever known.
"Because..."
He whispered.
"Sombra has never lied."
—
Outside the prison gates...
A black armored government SUV rolled slowly across the checkpoint.
Deputy Commander Héctor Alvarez stepped out wearing a freshly pressed tactical uniform covered in medals.
Reporters gathered behind the barricades shouted questions.
"Commander!"
"Do you think justice will finally be served today?"
"Any comment before the execution?"
Héctor flashed the perfect television smile.
"The justice system works."
"Today proves that no officer is above the law."
Camera flashes exploded.
Standing beside him...
A Belgian Malinois waited quietly.
Older now.
Larger.
His muzzle carried faint traces of gray.
Yet his amber eyes remained terrifyingly sharp.
Sombra.
The tactical leash rested loosely in Héctor's hand.
To every camera...
The scene looked heroic.
The decorated commander...
And the nation's most celebrated police dog.
No one noticed...
That Sombra never once looked at the reporters.
Never looked at the prison.
Never looked at Héctor.
Instead...
The dog's ears slowly rotated toward the prison walls.
His nose lifted into the cold morning air.
Then he froze.
His breathing changed.
Once.
Twice.
Three times.
He had caught a scent.
A scent he hadn't smelled...
In three long years.
Deep inside the prison...
Mateo.
The officers assumed the old dog simply recognized a familiar smell.
They couldn't have been more wrong.
Because Sombra wasn't recognizing a memory.
He was identifying something far more dangerous.
The same scent...
He had detected on the morning Captain Ruiz was murdered.
The scent of the real killer.
And that scent...
Was standing only inches away.
Holding his leash.
Héctor smiled confidently for the cameras...
Completely unaware...
That the one witness he had never managed to silence...
May you like
Walked beside him on four legs.
End of Chapter 1.
