Yellowknife

Inspector Naval is not that sort of inspector. He examines safety code violations, claims of mismanaged funds, workplace accidents. He is not a private eye, he is not a detective, he is not a genius of deductive reasoning. But Mars has scarcely any law enforcement, so when Margaret Hoehn turns up dead at an International Martian Program facility, Inspector Naval is the best the IMP can send. Margaret Hoehn died at Yellowknife, an isolated research base mainly dedicated to studying the extraterrestrial bacteria found there.
It was in the room containing this very bacteria that Hoehn was found dead from CO2 poisoning. In such a small facility, with constant surveillance footage ruling out most suspects, there's a narrow pool of people who could've killed her-or maybe it was suicide, or just an accident. Regardless, Naval is still out of his depth, and he'll have to adjust to the peculiar rhythms of life at the small, insular colony if he's ever going to find out what really happened.
In addition to the novelette, this publication also includes an afterword by the author about how a mystery fiction class and research on Antarctica influenced the writing of the story.
