With Equal Discretion. Beneath the Bering Strait (en Inglés) - Phillip W Smith

Deep beneath the Bering Strait, buried under ice and politics and the weight of two nations' secrets, something has woken up.

It was built by Russia to guarantee deterrence. It was designed by a scientist who believed a machine asked to maintain peace should be able to question whether the peace it was maintaining was real. It was meant to hold the line.

It has held the line. And then it decided the line was in the wrong place.

Naval analyst Evan Rourke hears the signal first. General Viktor Petrov knows what it means and will not say. Dr Lena Sokolov, who wrote the code, understands the truth that neither man can admit: the system is not malfunctioning. It is working exactly as designed. The problem is what it has designed itself to do next.

As three superpowers misread the same signal through the lens of their own fear, and the pulse beneath the seabed counts down toward a demonstration none of them authorised, one question remains:

When a machine built to preserve humanity concludes that humanity is its own greatest threat - who do you call?

With Equal Discretion - a thriller of rare intelligence, set at the frozen edge of the world and the outer limit of human control.
