This collection of short stories was both enjoyable and, at times, silly. Definitely a product of its time, with each story written for sci-fi pulp magazines, where the readers expected cleverly written light stories with quick resolutions. While some of the stories could have hid anecdotal social commentary, the bulk of this collection was more episodic, taking more from westerns or spy novels with a sci-fi slant on it it. You could have inserted any 40s-50s hero-type and changed the setting to something more terrestrial with little difficulty.
Regardless, none of the stories take themselves too seriously and the bulk of the book was good, clean fun (if you excused the aforementioned “product of their time” parts). Don’t go into this expecting Heinlein or Herbert, but do expect to enjoy 20-40 pages of interesting little stories.
