A techno-thriller duology by S.P. Mercer

What if the truth
had no source?

A CIA officer sees a Chinese general in Athens—while every intelligence system on Earth proves the man is in Beijing. Two realities. One missing source. And a war built from facts no one can trust.

SCROLL TO ENTER THE SIGNAL

Every fact is authentic.
Not every reality is.

Across fifty-two chapters and two connected novels, Zero Source follows veteran CIA officer Nick Alexiou through a geopolitical crisis where evidence can be genuine, systems can be correct, and the conclusion can still be catastrophically wrong.

From Athens and Beijing to NATO command rooms, hidden archives, and the machinery beneath modern intelligence, the duology asks one terrifying question: when our institutions can no longer agree on what is real, who gets to choose what we believe?

Two books.
One unbroken signal.

01BOOK ONE: The Things We Know by S.P. Mercer

BOOK ONE ZERO SOURCE

The Things We Know

An impossible sighting. A seven-minute discrepancy. A global crisis engineered from the truth.

CIA officer Nick Alexiou walks into an Athens restaurant and sees General Zhao Jianyu—a man every classified system proves is in Beijing. Then the records begin to multiply. Each is authentic. Together, they describe two incompatible realities.

02BOOK TWO: The Things We Believe by S.P. Mercer

BOOK TWO ZERO SOURCE

The Things We Believe

The evidence was real. The source was not. Now belief itself has become the battlefield.

The first crisis exposed a system that could manufacture certainty. The second reveals something older: an abandoned experiment, an archive that should be impossible, and a pattern that may have been shaping decisions for decades.

The systems
know everything.

01 / PROVENANCE

A man in two places.

General Zhao is eating grilled octopus in Athens. Satellite imagery, secure communications, and facial recognition place him in Beijing.

02 / CONVERGENCE

Proof without trust.

The data is not fake. The records are not forged. The danger lies in how authentic evidence is selected, connected, and believed.

03 / ZERO SOURCE

Certainty as a weapon.

ORPHEUS predicts. ARGUS challenges. Somewhere between them, another process decides when institutions should doubt—and when they should act.

“There are two reliable ways to know you’re getting old.”

S.P.
Mercer

Zero Source is a complete two-book techno-thriller about intelligence, artificial systems, institutional trust, and the human cost of manufactured certainty.

Written with dry wit, international scope, and the momentum of a modern espionage novel, the duology follows one continuous story from its first impossible sighting to its final reckoning.
