NanoStrike

Terrorists attack a London Underground train, slaughtering two-hundred innocents in seconds with a nanoweapon small enough to hide in a hint of perfume. First responder, Detective Chief Inspector Quinnborne, defies orders and hunts for the weapon's unhinged genius creator. The authorities label Quinnborne a traitor, but when the nanotechnology spirals out of control, his grit and bloody-minded determination become humankind's last thin hope of survival faced with a weapon of mass destruction that can be deployed at will and against which there is no defense.
