Contagion Option

IRON FIST Mack Bolan finds himself in a brutal war with a deadly international cartel that has been operating in secret for years. A terrorist group armed with nerve gas from one of America's largest bioweapons caches has set the stage for an endgame that could consign an entire city of innocents to an agonizing death. Bolan is surprised to learn that the containers were made in the U. S., but according to Stony Man records, they were destroyed in Utah more than four decades earlier.
The trail leads the Executioner to Asia and back to Salt Lake City, where one false move, one stray shot could unleash a lethal cloud on a city of millions.
