Out of the darkness, yellow and bodiless eyes peer into the faces of Doc Savage and his crew. And when Monk vanishes inside a locked room, Doc leaps to the rescue — plunging straight into a vicious international maelstrom that could change the course of history!
This had one of the best digest covers (by Modest Stein) and Bantam (Larkin). The story deals with an invisibility cloak that exposes only the eyes. It’s a slightly above average war-time Doc Savage novel that reads quite quickly. (It’s one of the Docs, like Whisker of Hercules) that takes a little from an earlier Doc (Spook Legion) and twists it around. It’s also a story that Dent seemed to enjoy writing. It zips right along and has some elements of humor in it.
