Lucky Starr and the Moons of Jupiter by Paul French (Isaac Asimov)
Hardcover: Doubleday, $2.75, 192pp, 1957
Lucky Starr and his sidekick Bigman Jones continue their tour of the Solar System, this time taking us as far as Jupiter where they have their most direct confrontation with the Sirian menace yet. Earth is secretly developing the first Agrav starship but the Earth’s power-seeking former colony is somehow pulling off an impossible job of espionage and finding out all about it. If Sirius gets the complete plans if and when the ship is successfully completed, it will mean war. Initially, Lucky is worried about telepathy and a V-frog (of a species introduced a couple of books back ) makes another appearance because Lucky’s thinking to set a telepath to catch a telepath. So the two men and their Venusian critter set out to Jupiter Nine to save the Agrav project. It quickly turns out that it’s not telepathy, but could be the Invasion of the Robot Body Snatchers. Fortunately, the V-frog will be useful for the task of identifying any robot spies, as well, since they lack emotion. Unfortunately, the V-frog is quickly killed. Fortunately, the pool of possible spies is reduced when the Agrav ship, the Jovian Moon, sets out on its maiden voyage with a limited crew, one of whom must be the spy. Unfortunately yet again, it turns out the ship is sabotaged and what had been a wondrous journey to see amazing Jupiter and its retinue of moons turns into a struggle against imminent destruction. Fortunately, yet again, the sabotage reveals the Sirians’ hand to Lucky, if only he can survive to use the knowledge.
In this Asimov completely takes off the Paul French gloves. Sirius is shown to be essentially a Spacer world. The notion of robots is central to this tale and, beyond that, the Three Laws are actually quoted in full in this one. Beyond that total-milieu similarity (or identity), there is also a bit of specific sameness to some of this in both good and bad ways. The good is that taking the reader to the worlds of the Solar System maintains its joy. The bad is that things like Lucky having to endure unfair hazing at the hands of larger, more skilled opponents (who lose anyway) lose their interest, as Lucky’s fight in the Agrav corridor with Armand is just like his pushgun fight in Pirates of the Asteroids. Lucky also behaves non-optimally more than once, such as when he provokes the Commander of the project due to a frankly silly supposed need to “field-test” the V-frog’s perception of emotions, which produces a continued struggle for dominance between the two throughout the book. The “puppy dog” aspect of Bigman’s relationship to Lucky continues, with Bigman getting excitedly playful and nearly dying when things go wrong, though he is given a moment to be clever in the way he evens the playing field (not too much, not too little) for Lucky in the corridor fight. Still, it’s another proficient Lucky Starr adventure (perhaps better than average though not the best) and will probably hit the reader however they’ve been hit by the other tales.
 All the previous books in this series are referenced in footnotes in the first ten pages of this one.

What did you think was the best one? Adolescent me liked this one the most, although half a century later, I’d be hard-pressed to say exactly why. Probably an enduring fascination with Jupiter and its moons, starting with when I read Heinlein’s “Farmer in the Sky.”

King of the planets! The setting (and the “up and down” of the moons rather than the “horizontal” view) is the best part of this and of most of them and I think that’s why I probably give Oceans of Venus the edge. My recollections of them blurred together and I was hoping one would stick out as clearly the best this time as a tip to people who wanted to try just one but none have really struck me as head and shoulders above the rest. One more to go, though! – so who knows? 🙂
I think my favorite Heinlein juvenile is Starman Jones, perhaps because that’s the only one I read as an actual juvenile (or perhaps because who wouldn’t want to be an astrogator?), but it held up (allowing for some loose structure in the back half) on my last re-read.
