MacGuffin: The Orotron, a machine that extracts minerals,
including gold, from sea water

Directed by: Ray Taylor, Lewis D. Collins

Plot: In the pre-World War II United States, a Nazi espionage ring--each member possessing a key to a headquarters control device--takes direction from an unseen leader, The Master Key. The focus of their efforts is Professor Henderson’s Orotron device, which can extract gold from sea water. Federal agent Tom Brant heads a spy-fighting trio that includes police detective Jack Ryan and reporter Janet Lowe. Who is The Master Key? An unknown foe or a false friend in disguise? You’ll have to wait until the final chapter (13) to find out for sure!

Review: “As with most Universals, plot and dialogue take precedence over fistic encounters but there is a good amount of action to keep me interested, and enough to keep me wondering who the Master Key really was. The chapters did not seem to drag on endlessly as is the case with some of the lesser Universals.” --39013
