Hit and run tale of international intrigue, inventive and highly active, -- as Alex Barker, a quiet man, is persuaded by his love for an English girl to team up with a Mr. Kats, diamond merchant, in his hunt for a syndicate selling industrial diamonds to the Nasin. With Barker as bait, Kats as brains, they round up enemies and diamonds after a pretty fancy game of bide and seek. Longish but good of its kind.
