Lucky Starr and the Pirates of the Asteroids by Paul French (Isaac Asimov)
Hardcover: Doubleday, $2.50, 188pp, 1953 
In this second adventure of David Starr, he takes one step further out to the asteroid belt and has awkwardly acquired his nickname of “Lucky” while Earth has suddenly acquired a Terrestrial Empire and even greater enemies than before, with a reborn pirate menace and active meddling by the shadowy Sirians.
The Council of Science thinks Lucky’s brought them a plan to booby-trap a spaceship that the pirates who infest the asteroids will seize and take back to their base, where it will detonate. But it’s actually Lucky’s plan to sneak aboard that ship and be captured by pirates so that that he can infiltrate their organization. When they arrive, they know all about the “trap” and Lucky pretends to be a poor sap who just wanted to stow away to get to them and obviously had no knowledge of the trap. When challenged, Lucky proposes a duel and the pirates agree, picking the style of combat. Lucky finds himself in a fight using “push-guns” (a sort of suit thruster) which he knows nothing about while the meanest pirate, Dingo, is an expert. Nevertheless, the pirate makes a couple of mistakes and Lucky comes out on top. Still suspicious of Lucky, they drop him off at a hermit’s asteroid while they head back to base to check him out further. He and the hermit trade infodumps and the hermit recognizes Lucky as the son of Lawrence Starr. He sees in this a chance to return to civilization with a pardon for his collaboration with the pirates if he can save Lucky and provide information about the pirate operations. He convinces Lucky that the pirates will see through Lucky’s game and they both return to Ceres, where friend Bigman and “parents” Henree and Conway have a joyous reunion.
One thing perplexes Henree and Conway though, and that’s how the pirates could have known about the trap. They decide there must be a spy in the Council of Science who is leaking information but Lucky reveals that he is the spy, though he had his reasons. Then he decides to try again, this time with Bigman playing the pirate infiltrator. Like Lucky, Bigman does some freelancing of his own (no wonder they’re pals) and, like Lucky, he also fails because it turns out the asteroid is lost. For reasons given later, the mystery of the asteroid makes Lucky realize the Sirians and their pirate tools intend to take over the solar system, and quickly. Lucky must go out in his own super-spaceship to pick up Bigman and try to reverse-engineer the location of the hermit’s asteroid. Finding it, Lucky is again captured, Dingo again makes a mistake, Lucky again comes out on top and, among Lucky’s subsequent efforts to prevent the Sirian takeover of the Terrestrial Empire, he must put his ship on an intercept course with another pirate ship which involves flying through (the corona of) the Sun.
And some of what I’ve just told you isn’t really what was going on because, in addition to Asimov having Lucky and Bigman repeatedly trying to trick others and repeatedly having others try to trick them, Asimov is also trying to trick the reader. This isn’t always entirely successful and the plot doesn’t bear too much scrutiny. For instance, the pirates such as Dingo and Anton (the latter of whom, at least, is supposed to be intelligent) repeatedly behave stupidly from self-defeating spite, Lucky is recognized twice in two books despite Councilmen not being publicized (and in the first book his nom de guerre was “Dick Williams” and in this it’s “Bill Williams”), and so on. In addition to the inconsistency of the famous unknown Starr and the things I mentioned in the first paragraph, Earth was dependent on Mars for food in the last book but, in this one, it’s Venusian yeast cultures which figure prominently.
Given that large populations eating yeast is a significant Asimovian motif, its clear that Asimov is erasing what little division there was between “French” and himself, which is confirmed by the use of “hyperatomic motors,” “personal capsules,” “neuronic whips,” and other standard furniture of Asimov’s futures. (Unfortunately, it also repeats a common Asimovian tic of throwing in a named character (such as the “good pirate” Martin Maniu) to serve his brief purpose and then dropping him.) Conversely, all the space battles and other fights made me think that this book was almost to Asimov as the atypical Earthlight was to Arthur C. Clarke.
In terms of hitting the target audience, this may be slightly more juvenile than the first book, as the hazing Lucky endures from the head pirate, Anton, and the “game” (albeit a potentially deadly one) of the push-guns indicate. Also, the style is generally fine but the pirates have strange lapses such as Anton “suavely” explaining to Lucky that pirates call “asteroids” “rocks” and Dingo’s first line being, “Blinking Space, there’s a ripper with a gat here!”  Either way, most of its young audience of 1953 probably would have enjoyed it quite a bit.
For a general audience, Asimov does achieve the neat trick of creating a Foundation milieu which is huge in time and space but feels proportionally smaller than one might expect a galaxy to feel, while creating a Starr milieu in which the Solar System seems quite large. More importantly, the sense of multiple vise grips being applied to the Terrestrial Empire by the pirate and Sirian menaces, coupled with Lucky’s thrilling high-speed burn through the System and the Sun in pursuit of pirates is all very effective. Again, this is surely secondary Asimov but is not without its virtues. Speaking of, its edifying ending may also have aspects of a “message” to young readers (and certainly isn’t how I would have handled it had I been in Lucky’s shoes) but makes for a satisfying conclusion to this installment.
 Again, I’m using the Del Rey cover as explained in the David Starr review.
