Tunnel for Traitors

The Soviets have perfected a new military device.

The weapon: A low-level particle beam laser gun.

The target: American communication and military intelligence satellites.

The solution: An American tunnel beneath the Berlin Wall which taps into a terminus of telephone cables serving both East German and Soviet headquarters. If the tunnel lasts only a month, it will be a brilliant espionage coup.

But a security leak has been uncovered in West German Intelligence. A mole, an informant and he must be stopped. Enter Agent N3 Nick Carter....The Killmaster.
