Three hundred meters below the surface. One dead officer. No way out.

When Lieutenant Commander James Wearing is found dead aboard HMS Valor, the Royal Navy's most advanced nuclear submarine, it's ruled an accident. A tragic electrical mishap during a routine patrol.

But Dr. Blake, the boat's medical officer, knows better.

The burns are wrong. The timing is wrong. And as Blake begins to investigate, he discovers something far more dangerous than murder: HMS Valor has been compromised. A sophisticated espionage network has infiltrated the submarine, stealing classified intelligence and transmitting it to an unknown enemy. The conspiracy reaches into the highest levels of the Admiralty—and the traitors are still aboard.

Trapped three hundred meters underwater with a crew of suspects, Blake must identify the killers before they can silence him. But in the claustrophobic depths of a nuclear submarine, everyone has secrets. The cook. The sonar chief. The steward. The navigator. Any of them could be SHEPHERD's operative. Any of them could strike next.

And when a hostile submarine begins tracking *Valor* through the North Atlantic, Blake realizes the conspiracy isn't just about espionage—it's about ensuring the boat never makes it home.

A taut psychological thriller combining the tension of The Hunt for Red October with the paranoia of Tinker Tailor Soldier Spy. Perfect for fans of Tom Clancy, John le Carré, and submarine warfare fiction.

No safe harbor. No reinforcements. No one to trust.
