My Best Friend's Double

My childhood best friend lost contact while working deep undercover abroad. I immediately filed an application with the department to go in and assist him.

When I finally found him, he was rotting. He had been tortured beyond recognition in a dark basement. But thankfully, he never opened his mouth. He kept his cover, and he kept his life.

Over the next few years, the two of us worked in perfect, silent sync. Step by step, we climbed the ranks until we became the top two lieutenants of the cartel. We got closer and closer to the very core of the organization. Finally, on his 33rd birthday, we took them all down. The mission was complete.

Looking at the plane tickets back home in my hand, my eyes suddenly welled up with tears. I hadnt even flinched when I took a bullet to the shoulder last year, but now, I was sobbing.

"Leo, our parents are avenged. We can finally go home."

I was just about to pull out the birthday gift I had prepared for him when Leo suddenly sighed. "Yeah. Its been so long. I wonder if the old oak tree we used to climb still stands."

His eyes were red with emotion, but my heart stopped. A cold dread washed over me.

Our parents had both been brutally murdered by drug traffickers when we were kids. Before we even entered the police academy, we knew we would face these monsters eventually.

Back then, I suggested we cut our palms and become blood brothers, so that if one of us died, the other would carry on for both of us.

But Leo had pointed at the oak tree in the backyard and said, "Were already brothers, Mason. We dont need a silly ritual. The ashes of our parents are buried right beneath this tree. All we need to do is get revenge. If there ever comes a day when one of us is captured, we must find a way to say the words 'blood brothers' to the other."

"It means: *Im compromised. Do not believe a single word I say.*"

But right now, we were completely safe. And yet, he had just looked me in the eye and brought up that tree.

He wasnt Leo.

Then where was my best friend?

Who was this man who had stood by my side, risking his life on the edge of a knife, fighting with me for years?

Noticing my sudden stiffness, "Leo" looked at me with concern.

"What's wrong, Mason?" he asked, his voice dripping with worry. "Is the PTSD kicking in? I know the pressure of the last few years has been insane."

Looking at the genuine concern in his eyes, I forced myself to relax slightly.

My parents and his parents had been partners on the force. They were brutally tortured and killed by the cartel when we were young. Since then, I had suffered from severe insomnia and clinical anxiety.

But I had Leo. Even though we were the same age, he was always the mature one, the strong one.

With his help, I slowly put my shattered mind back together.

Only Leo knew about my mental struggles.

And I knew his face better than my own. The man standing in front of me looked exactly like my best friend. Even the tiny, faint scar near the corner of his lip was identical.

Maybe he was just overwhelmed by the end of the mission? Maybe he actually forgot our secret code in the excitement?

I decided to test him. "I'm fine. It's just... when you mentioned the oak tree, I felt a pang of guilt."

"During the months you went missing, some cartel clean-up crew tracked down our old place and set it on fire. I was too busy preparing for my own undercover deployment to notice. The fire killed the tree. It burnt to ashes."

His eyes widened in shock. "Burnt? But our parents ashes were buried under it! Mason, did you manage to save them?"

The burial of our parents' ashes was a secret.

No one in the world knew about it except the real Leo and me.

My heart eased slightly. I was just about to answer when "Leo" rubbed his red eyes and sighed.

"Forget it. What's done is done. Don't beat yourself up, Mason. We brought down the cartel. We got justice for them. Their spirits will understand."

He smiled warmly, placing a hand on my shoulder. "Besides, we are blood brothers. Whether the tree is there or not, we are brothers forever."

The words I was about to say choked in my throat like a fistful of dry gravel.

He said it again. *Blood brothers.*

If he had forgotten the code the first time, there was no way he wouldn't have remembered it now.

This was the sacred oath he made me swear the night before we entered the academy.

It was about life, death, revenge, and our absolute core belief. We had branded those words into our very souls.

"Yeah," I forced a smile, my voice barely a whisper. "We'll always be brothers."

"Leo, today is your birthday. Lets not talk about sad things."

I subtly stepped back, breaking his touch, and pulled out the watch I had customized for him.

Suddenly, my hand slipped. The watch hit the hard tile floor.

The glass shattered.

"Oh, damn it!" I gasped. "I am so sorry, Leo. Let me get this fixed. I'll get you another one."

He waved his hand, smiling. "Its fine, man. I don't care about material stuff."

But I insisted. I told him I couldn't leave the country without giving him a proper gift. I canceled our flight tickets.

I needed to find my best friend on his birthday.

Dead or alive.

***

While waiting for the new gift to be ready, "Leo" took me to a local arcade.

He knew exactly what games I liked to play when I needed to decompress. He even remembered my favorite characters and combos.

When I reflexively used my teeth to pop open a soda bottle, he frowned, grabbed the bottle, and scolded me just like the old days, nagging about germs and dental bills.

Apart from the "blood brothers" phrase, he was perfectly, flawlessly Leo.

"Mason, the last time we celebrated our birthdays together was five years ago, right?"

During dinner, before I could even probe, "Leo" brought up the past. "I went behind your back and applied for the undercover op. When you found out, you lost your mind. We got into a massive fistfight."

"But you lost," he chuckled, lighting a cigarette, his eyes filled with nostalgia. "You were so mad you cried and stayed up all night."

I remembered that night.

We had agreed that I would be the one to go undercover.

Leo had smiled and agreed to my face, but then stole the assignment behind my back.

He wanted to sacrifice himself to protect me.

He was the same age as me, but he always acted like a protective big brother.

But was that Leo still alive?

I clenched my fists under the table, forcing a chuckle. "Of course I remember."

"You went back on your word. I was so desperate I wanted to call Director Miller to beg him to swap us. What did you do then?"

He laughed harder. "I confiscated your phone and locked you in your room. By the time you broke the door down, I was already on a flight out of the country."

I tried to laugh with him, but my facial muscles felt frozen.

Our fistfight was public knowledge among a few close colleagues back at the precinct.

But the part about him locking me in my room? Leo would have never told a soul. It was embarrassing and highly unprofessional.

Yet, this man knew. He knew every single detail.

How? How could he know so much?

In the silence, "Leo" suddenly stood up and reached over with a napkin.

"You still eat like a toddler. Wipe your mouth. How am I supposed to set you up on dates back home if you eat like a pig?"

His nagging was so familiar, so warm, and so frustratingly comforting.

My vision blurred. Memories of the years we spent relying only on each other rushed back. I wanted so badly for him to be real.

Then, the final dessert was serveda classic Peach Cobbler.

I had ordered it on purpose.

I stared intensely at his face. I saw him freeze for a second, and then his eyes turned red.

"Our parents loved peaches," he whispered softly. "It's a pity our 'blood brother' oak tree is gone. I wonder if they missed the sweet smell of peaches these past few years."

Every ounce of warmth in my chest vanished instantly. My mind went ice-cold.

He said it again. *Blood brothers.*

Once. Twice. Three times.

He was not Leo.

My instinct was to tackle him, call the local backup agents still cleaning up the city, and beat the truth out of him.

But I didn't dare.

If the real Leo was still alive somewhere, any reckless move on my part could get him killed.

I had to play along. I had to find out where Leo was.

***

But I couldn't understand. When did the swap happen?

Three years ago, Leo went dark. Out of the four undercover agents our department planted in the cartel, three were tortured and killed. Leo was the only survivor, but we lost contact with him.

Everyone thought he was dead.

Without hesitation, I volunteered to take over the mission. Three months later, with the department's help, I managed to get close to one of the cartel's mid-level bosses and successfully infiltrated the syndicate.

That was when I saw Leo again.

He was chained to the wall of a damp basement. His body was a map of raw, infected burns and cuts. He looked half-dead, but it was him.

The boss who brought me down there laughed and said, "We probably got the wrong guy. The Big Boss suspected he was a fed, but no cop could survive six months in this hole without singing."

I didn't dare show any emotion.

In the brief second our eyes met, Leo looked at me. He was in agony, but his eyes were sharp, fierce, and unbroken.

He silently mouthed five words: *Don't worry. I'm okay.*

I almost broke down right then and there.

He had survived the torture that we thought no human could withstand.

I was 100% sure that the Leo in the basement three years ago was the real Leo.

Later, he cleared his name, got promoted within the cartel, and we started working together. He never betrayed me. In fact, he saved my life multiple times.

So, the Leo of the past three years must have been real too.

Exactly when did this impostor take his place?

I racked my brain, but I couldn't find a single gap.

"Mason, the gift should be ready by now," "Leo" said as we walked out of the restaurant. "Let's grab it, book the earliest flight, and head home."

I couldn't make up any more excuses to delay.

I pretended to have a sudden, agonizing stomach cramp. I locked myself in a bathroom stall and messaged my handler, asking him to send over every encrypted log of our communication during the undercover years.

We had pretended not to know each other, communicating only through cyphers left at dead drops.

I needed to read every single word. I needed to analyze the syntax, the slang, the tiny habits to see if there was a shift in tone.

But after reading them three times, I found absolutely nothing.

Outside, "Leo" knocked on the door.

"Mason? If your stomach is that bad, I'll run to the pharmacy. If we delay any longer, were going to miss the red-eye flight."

His voice made my skin crawl.

A sudden, terrifying thought hit me.

What was the point of this impersonation?

***

If he was an impostor, to know these intimate details about our childhood, he must have captured the real Leo and tortured the information out of him.

But if he had already captured Leo and compromised us, why did he let the entire cartel get destroyed?

And now, instead of running away with his money, he was actively trying to enter the United States with mea place where law enforcement would make his life ten times harder.

"Mason!"

"Talk to me, man!"

"You didn't pass out on the toilet like Wyatt did back in academy, did you?"

He sounded genuinely worried, knocking louder.

"I'm coming out!" I called back.

The puzzle pieces weren't fitting.

If he wanted to fool me, knowing my childhood was enough. Why would he remember a stupid story about our classmate Wyatt passing out in the bathroom six years ago?

Even under extreme torture, no cartel interrogator would ask about classmate gossip.

And Leo would never crack.

His conviction was absolute. He would never bow to these monsters.

I walked out, and he immediately checked my forehead for a fever. His worry looked 100% real.

Could it be... that the years of psychological trauma had messed up Leo's mind? Had his memory fractured, making him truly believe we had a literal "blood brother" ritual?

That was the only logical explanation left.

"Leo, let's go to the hospital," I muttered, holding my stomach. "I think my ulcer is flaring up again."

Before I could finish, "Leo" grabbed a passing waiter. "Where is the nearest ER?"

Once he got the address, he threw my arm over his shoulder and practically carried me to a cab.

He didn't even look this panicked when he was chained up in that basement.

My throat tightened.

I wanted to believe he was real.

I went to the hospital to buy time. I had secretly messaged a local backup agent to meet us at the hospital and quietly collect a hair sample from "Leo" for an express DNA test.

If he was the real Leo, we would go home together.

If he was fake, I would arrest him right there.

I managed to snag a few strands of his hair from his jacket and handed them to the undercover agent in the hospital hallway.

The next twenty hours of waiting felt like a slow death.

Finally, my phone buzzed.

*DNA matches Leo Vance. The sample is clean. He is who he says he is.*

The moment I read the text, I let out a breath I felt like I'd been holding for years. I could finally breathe.

I ran back to his room. "My stomach is fine now, Leo. Let's go home! Let's get the hell out of here!"

He grinned, relieved, and immediately pulled out his phone to book the flight.

In the Uber to the airport, I finally let my guard down. We talked about where wed go for vacation, and how we would take our parents ashes to all the places they had wanted to visit but never got the chance to.

It felt like stepping out of hell straight into heaven.

Knowing Leo was alive and safe was all that mattered.

"Oh, wait"

As we pulled up to the airport terminal, "Leo" suddenly snapped his fingers. "We don't have much savings, and the department's bonus is going to take months to clear probate. We don't have the cash to travel right now, do we?"

"How about we dig up the stash our parents left us? We agreed back then that once we got revenge, we could finally use it."

My body went completely rigid. "What stash?"

"Leo" laughed naturally. "What do you mean, 'what stash'? Did you forget?"

"The cash we buried under the Tree of Wrath."

My eyes widened. Cold sweat broke out across my entire body, and my blood turned to ice.

There was no "Tree of Wrath."

There was only the oak tree.

"Tree of Wrath" was a code word we used to describe our target list. It was a psychological tool we created to keep our hatred alive, to remind ourselves never to compromise, never to give up.

And there was no treasure.

Only our parents' ashes.
