Protocol

PROTOCOLA Shadowboxer FileA 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.
