Doc Savage informs the Admiral that the
villain is John Sunlight and that he has Doc's Superior Wave
Modulator. Doc contacts Renny and Long Tom who are passing through
the Panama Canal in the Helldiver submarine, telling them to set
course for Phoenix Island. They tell him that Pat flew off on her
own....
Pat, meanwhile, uses a caustic chemical
concealed in her belt (courtesy of Monk) to burn through the lock on
the cell. The two heroines then overpower some guards and take their
weapons....
After telling the Admiral that if they
do not return in 72 hours to bomb Phoenix Island off the map, Doc and
company head for the island in their plane. On the island, John
Sunlight greets his visitors, a delegation from the Japanese Empire,
who are interested in this new weapon. Sound of gunfire from Pat and
Amelia, with the notice that Doc's plane is on the way, compels
Sunlight to offer a demonstration of the Modulator. Doc and his men
parachute to the island; Doc is separated from the others and is soon
surrounded by John Sunlight and his men....
