Prison Code — Don Pendleton

NUCLEAR LOCKDOWN

When a plot to unleash weapons of mass destruction on U.S. soil is discovered in a coded message, all clues lead to the country's most notorious prison in upstate New York. With time running out, Mack Bolan goes in undercover as an inmate to find out who's behind the attack and stop it from happening.

Surrounded by corrupt guards and convicted killers who want him dead, Bolan can't trust anybody-and one wrong move could be lethal. Weaponless and cut off from the outside world, he's aware that the only tools he has to track down the nuclear devices hidden in the prison walls are psychological warfare and hand-to-hand combat. This high-security facility may have been designed to keep the deadliest criminals in check, but nothing can keep the Executioner down.
