Plot
Returning to Mars from a four-year stay on Earth, sixteen-year-old Nelson Parr feels anger toward all the talk he hears about the possibility of the Earth authorities shutting down the Martian colony and bringing all of the colonists back to Earth. For a century the colonists had tried to make a living on Mars and, more importantly, to unlock the secrets of the abandoned cities that they found on the planet and now some people just wanted to give up. He’s distracted from his anger when he’s attacked by an intruder in his sleep cubicle. The assailant gets away but leaves behind, on the mirror over the wash basin, the evaporating print of a three-fingered hand. Nelson assumes that the burglar was looking for the letter that Leroy Perrault, a scientist with the Interplanetary Bureau, had given to him to pass on to his father, John Carson Parr. After arriving on Mars Nelson learns from his father that the planet is indeed being abandoned and over the next few days the remaining three hundred colonists are put on ships and sent to Earth. But Nelson, his father, his father’s assistant (Jim Worden), and three other men secretly stay behind. Perrault’s letter has authorized this clandestine group because certain anomalous events noticed over the previous century indicate that the Martians are still present, hiding in their impenetrably sealed cities. To catch out the hidden Martians the six men ride a small rocketship to Phobos, the larger and innermore of Mars’s moons, and set up camp with their telescopes. Weeks go by, but then Nelson sees a light in one of the cities. Over the following days the men see more signs of activity in the city and one day they see a collection of crates lying in a plaza. To keep a longer watch on the crates Nelson and Jim take their rocketship’s lifeboat to Deimos and set up the spare telescope some distance from their landing site. Jim goes back to the lifeboat to get the telescope’s other lens and when he doesn’t come back after some time Nelson goes to see what’s taking him so long. He finds that Jim has been murdered: someone bashed in the back of Jim’s helmet to let the air out of his spacesuit and then sabotaged the lifeboat and its radio. Trying to spot the murderers while at the same time evading them, Nelson crosses the surface of Deimos in long, gliding bounds, hoping, in some desperation, to find the killers’ spaceship and somehow take it. Feeling that he’s being followed, he hides in a small, narrow canyon and, believing he’s under active pursuit, goes to its dead end and takes refuge in a cave that ends at a door. He hides in a side tunnel and watches five humanoid aliens come to the door, open it, and pass through. A few minutes later he goes through the door, through the airlock beyond, and into a large alien base under the surface of Deimos. As he’s exploring the base he’s confronted by one of the three-fingered aliens, who introduces himself as Kunosh, the leader of the Deimosians. Hearing of Jim Worden’s murder, the timid Kunosh enlists Nelson’s help in ridding Deimos of certain bad men who, Kunosh assures Nelson, killed his friend. In the control room of the hollow moon Nelson knocks out the five aliens who he believes killed Jim, enabling Kunosh’s people to tie them up. Then he finds out that the five came from Phobos, where his father and three other men are at risk. In response to Nelson’s demand and the taunts of one of the Phobosians, Kunosh tells Nelson that his people, both Deimosians and Phobosians, are not Martians. These aliens had originated on a planet revolving around the starPublication history

The book was reviewed by *An anonymous reviewer in Kirkus Reviews for 1955 Sep 09. The reviewer wrote: “A jaunty story, somewhat more humorous and lighthearted than the others in this series, takes young Nelson Parr, a Terrestrian born in the Martian outpost and research center, through a set of adventures that unlocks Mars’ secret. A political controversy is raging on Earth as to whether or not to continue to support the Martian outpost, where Nelson’s father is research chief. Those in favor point to the marvelous machines found on Mars, any one of which could advance civilization eons, if their secret could be discovered. Going to work on the problem, Nelson finds out – in an interesting chain of events that characterizes a Mars basically like the canal-covered red planet we know it to be now – that the Martian moons Phebos (sic) and Deimos, are centers of tyrannical factions that have kept Mars in sub-jugation. Phebos (sic) and Deimos are vanquished and all is well.”References
