Malka Older’s 2022 The Mimicking of Known Successes is a stand-alone science fiction mystery, one of the Holmes and Watson variety.
Thanks to humanity’s communal quest for profit, Earth is uninhabitable. Indeed, such was human diligence in this matter that even Mars was somehow made even less habitable. Only on a single giant planet1 do the remnants of humanity survive. They have finally embraced more responsible behavior; the alternative is total extinction.
It’s no utopia. Thus, police. Thus, missing persons cases — possibly murder cases — for said police to investigate.
A stranger vanished from a remote railcar station. No railcar had arrived to bear him away, suggesting he plummeted from the station into the giant world’s depths. Did he commit suicide? Was he murdered? In either case, why? Investigator Mossa is determined to find answers.
