The Petrograd submarine, Russia’s newest and deadliest war-toy, is NATO’s worst nightmare. So, when a Russian naval officer offers the sub’s plans and maintenance manual for sale, the CIA station chief in Tokyo jumps at the chance. Both get more than they bargained for. Hours later Russian-seller and CIA-buyer are dead-gunned down by the KGB. But the microchip with the plans has vanished.

With the plans up for grabs Tokyo becomes a chess board of intrigue in a deadly game of Far Eastern espionage. But the Killmaster is playing for higher stakes. As Soviet and Western agents clash, N3 goes after the sub itself...

They call him Reguiba. Moroccan death merchant extraordinaire. With an army of desert jackals who live to kill-and kill to live-he’s got the manpower, the hardware and the petrodollars to pull any job... no matter how bloody.

His target: American allies in the Middle East. His goal: the total breakdown of Western alliances. His biggest obstacle: Agent N3 — Nick Carter!

They’re a mercenary elite who’ll take on any job-the more murderously spectacular the better — if the price is right. But their ultimate purpose isn’t wealth; it’s power in its most raw and devastating form.

They call themselves the Law of the Lion. Their base is the treacherous jungle of Central America. And they hold no loyalty to any cause but their own. They’re the most awesome terror army the world has ever faced — and challenging them on their own turf is like diving into a pool of blood in shark-filled waters.

Only Nick Carter would try it. Only Nick Carter could win.
