Protocol

A Shadowboxer File

A scientist disappears.

Her research could kill millions.

When intelligence operative Brill Wingfield gets the call, the clock is already running. Dr. Lena Farstad—an aerosol chemist working in Lisbon—has been kidnapped along with the prototype of a breakthrough biological delivery system.

In the wrong hands, it isn’t just dangerous.

It’s a weapon designed to target people by their DNA.

The buyers are already negotiating. Forty-two million dollars for a technology that could rewrite the rules of warfare and turn genetics into a death sentence. If the deal closes, the weapon disappears into a conflict where no one will even understand what killed them.

Brill has less than forty-eight hours to find Farstad, destroy the samples, and stop the sale.

But the deeper he digs into the operation—through freight brokers, mercenary middlemen, and a ruthless Russian broker known as Vashko—one thing becomes clear:

Farstad may not want to be rescued.

Because the scientist who built the weapon is racing to finish something of her own.

A final protocol.

And if Brill doesn’t figure out what it is before the buyers arrive, the operation meant to stop a catastrophe may be the very thing that triggers it.

PROTOCOL is a razor-sharp international thriller packed with covert operations, high-stakes science, and the cool professionalism of operative Brill Wingfield.

Perfect for fans of Lee Child, Mark Greaney, and Daniel Silva.
