Pro the Assassin's Code: Assassins Rule the Shadows

By Geoffrey Zachary

Pro: The Assassin's Code

Tagline: Assassins Rule the Shadows.

They trained him to be invisible.

They built him to be unkillable.

They coded him to follow orders-without question.

But Gabriel Voss-codenamed The Pro-just broke the only rule that matters: he walked away.

Now, the most dangerous killer alive is the target of a global manhunt. Not by police. Not by armies. But by a secret brotherhood known only as The Creed-a centuries-old order of assassins operating behind governments, corporations, and proxy wars.

The Pro was once their best.

Now he's their greatest threat.

After a high-profile kill goes wrong in Prague, Gabriel uncovers a chilling truth: his target wasn't just a corrupt official. He was a deep-cover agent trying to expose Orion-a next-gen protocol designed to manipulate geopolitics through precision assassinations. Worse, the job was issued by a ghost client no one can trace.

From the underbelly of Moscow to the neon-lit rooftops of Seoul, from war-torn deserts to snow-covered mountain fortresses, The Pro begins a ruthless pursuit of the truth. Alongside a rogue MI6 operative, Elena Frost, and an off-grid hacker codenamed Cipher, he must navigate a labyrinth of betrayals, encrypted kill lists, and shadow councils shaping the world behind closed doors.

But this isn't just a mission.

It's personal.

Years ago, The Pro spared a life, against The Creed's command. Now, that one act of mercy may be the key to unraveling everything... or bringing it all crashing down.

As old enemies rise, allies fracture, and a new breed of cyber-enhanced assassins emerge from the shadows, Gabriel must face the ultimate question:

Can a man programmed to kill ever choose to stop?

What's Inside:

- Brutal, cinematic action scenes worthy of John Wick, Jason Bourne, and The Gray Man

- Intricate conspiracies and code-based mind games reminiscent of Tinker Tailor Soldier Spy

- Morally complex characters walking the tightrope between justice and survival

- An international race across 20 PLUS exotic, gritty, and high-stakes locations

- A lone assassin's journey from hunter to hunted... to legend

The Creed has rules. Gabriel Voss has none.

Every assassin follows the code. But only one dares to rewrite it.

Pro: The Assassin's Code is the explosive first installment in a globe-spanning crime thriller saga. With relentless pacing, razor-sharp prose, and heart-stopping twists, this is a story about control, corruption, and what it truly means to be free.

Adaptation Potential:

- High-octane series with streaming franchise appeal

- Cross-platform ready: Books, games, TV, and film

- Franchise-defining tagline: "There's always a Pro."

Perfect for fans of:

- Mark Greaney's The Gray Man

- Lee Child's Jack Reacher

- Greg Rucka's The Old Guard

- Tom Clancy's Splinter Cell

- John Wick / Jason Bourne / Sicario

The Creed may fall... but the code lives on.

And in the shadows, one name will always rise:

The Pro.
