The Death Dealers — Mickey Spillane

The Mann's back, playing it low and deadly in a last-chance game of international espionage.
 
Tiger Mann, America's superspy, outwits an ace Soviet agent, foils a plot to kill a king, and takes the ruby from the navel of a restless Arabian dancer. All for the good of his country. No one but Mann and his ultrasecret organization could handle such a hazardous mission. No one but Spillane could write such a roaring hell-raiser of a thriller.
