TOM SWIFT AND HIS
JETMARINE

by VICTOR APPLETON II
 

The jetmarine, the second great invention of Tom Swift, takes the young inventor into a desperate battle with bold modern pirates who have been ravaging the sea lanes. Attacking with a sinister blackout weapon, the Sea Snipers have sent a passenger liner to the bottom — and Tom's chief engineer is missing!
    The treacherous enemy pulls no punches in trying to wreck Tom's atom-powered submersible, able to travel faster and deeper beneath the seas than any craft known to man. From the warm Caribbean to the coast of Portugal, the pace con- tinues on and under the sea, in the air, in a haunting sea-bottom der- elict, and in the raiders' hidden sanctuary beneath the waves. Finally an audacious race to break the speed of sound underwater becomes a race against time to save America's Atlantic coast from dis- aster!
