It started when a Viking Dragon ship attacked a yacht in the waters outside New York. Next, Ham was stabbed with a 1,200 year-old Viking knife. Then Johnny was captured and frozen solid in a block of arctic ice. Finally, even the mighty man of bronze himself - Doc Savage - is kidnapped and enslaved by the chilling menace. What is his plan this time? Can he save himself and his friends from almost certain destruction?
