Truth is never what it seems.

When a body is found on a train arriving in Zurich, Inspector Lea Keller is called to what should have been a routine investigation.
But the autopsy reveals something no one expected a second puncture, a dose that could not have been accidental.
The deeper Keller looks, the more the case pulls her toward the quiet corridors of a pharmaceutical giant, where silence is policy and compliance is weaponized.

A missing researcher.
A whistleblower erased.
A message from a man already dead.

As Keller pieces together the fragments of a buried truth, she is forced to confront not only the system that hides behind legality but her own belief in justice itself. In a world built on reports and signatures, what does it mean to tell the truth and who pays the price for it?

Taut, elegant, and psychologically exact, Below the Surface is a literary thriller about the cost of integrity and the thin line between revelation and ruin.
