Dr. Roj Nemennuh Sarton

Dr. Roj Nemennuh Sarton is the scientist whose murder sets the investigation in motion and gives it stakes beyond identifying a killer. For Spacetown, the case is also a political test: failing to pursue it would strengthen opponents of the settlement on Earth, even though punishment could not bring Sarton back to life.

Identity and Place in the Case

Sarton is referred to in the investigation as Dr. Sarton and is already dead in the evidence presented here. His murder is treated as a consequential crime involving a blaster, but the weapon is never recovered. The evidence does not further describe his work or personal history; instead, his significance emerges through the investigation’s accumulating clues and the political consequences attached to resolving his death.

The Missing Weapon

The inquiry establishes that a City-dweller present at the scene initially became a suspect, but was quickly cleared: he had entered Spacetown through the usual procedure, under which blasters were removed. The checks of every blaster in Spacetown found that none had been fired for weeks, and an examination of the radiation chambers supported that finding. The murder weapon remained missing.

That absence becomes a central constraint in the reconstruction. The scene had been searched minutely, yet the blaster could not simply have vanished. In discussing the possibilities with Dr. Anthony Gerrigel, the investigators reason that R. Daneel Olivaw was at the scene and, apart from the possibility of an Earthman crossing open country with a weapon, was the only person there who could have hidden it. This is presented as a deduction about opportunity, not as proof that R. Daneel Olivaw fired the weapon: he explicitly says he did not shoot.

Political Stakes and the Investigation

Spacetown’s purpose, as described in the investigation, is to break Earth’s isolation and encourage renewed expansion and colonization. Sarton’s murder therefore carries a political danger for that project. The case is not pursued on the premise that punishment could restore the victim; rather, Spacetown fears that failing to seek justice would strengthen politicians on its home world who oppose the settlement itself.

As the inquiry nears its answer, Spacetown is preparing to leave Earth of its own accord. Elijah Baley takes that withdrawal, alongside efforts to remove him from the investigation, as a sign that the solution is close, though at that moment he has not yet worked it out. The case thus shifts from a question of evidence alone to a race against political retreat and the threatened end of the inquiry.

Resolution and Narrative Significance

At 23:00, Baley declares that he knows who is framing him, how Sarton was killed, and by whom. He has one hour to explain the solution, catch the person responsible, and end the investigation. The supplied evidence stops at that announcement, so it confirms that the case’s resolution includes both the murder and an attempt to frame Baley without yet supplying the promised explanation.

Sarton’s death consequently functions as the hinge between a murder puzzle and a larger conflict over Earth’s future. The missing weapon tests the investigators’ assumptions about access and opportunity; the political argument makes the pursuit of an answer matter even when it cannot undo the loss. The final deadline compresses both stakes into a single unresolved task: expose the framing and identify the killer before Spacetown’s investigation is over.
