It seems to be an open secret that "Paul French" is Isaac Asimov; and the latest adventure of Lucky Starr ["Lucky Starr and the Oceans of Venus"] is the first in this series to deserve comparison with Asimov's often admirable adult science fiction. Here he has dropped the foolish trappings which made earlier books seem like a blend of Space Patrol, Superman and the Lone Ranger, and devoted himself to a straightforward, near-Heinlein adventure on Venus—a tight, fast story, including a well-plotted detective puzzle and some excellent xenobiology—which, for the uninitiated, means the study of possible non-Earthly life forms.
