The scenes of this thrilling story vary from Havre and Paris, to the romantic islands of Polynesia, where the last threads of the plots are finally untangled. John Crane, a middle-aged man of wealth and adventure, is asleep on his ocean-going yacht in the Port of Havre, when he is unduly awakened in the wee small hours of the morning upon the insistance of an Englishman, just arrived from Paris by motor. The Englishman reveals himself as a friend of Martin Todd, an old pal of Crane's, who has agreed to help a group of Russian Noblemen in an endeavor to smuggle some valuable jewels out of Russia. Crane, of course, is eager to accept the jewels and guard them, although he is warned that Soviet agents will cause trouble. And thus the plot is launched. Next the scene shifts to the Paris Underworld, where Anne Walton, the daughter of a rich planter, is discovered on an errand of mercy. A gripping, hair-raising story.
