Sci-fi spaceship
Eight light-years from home, an airlock opens — all by itself?
Claustrophobic sci-fi aboard a spaceship. The murderer doesn't know their own guilt — the system reveals it to them late in the game.
The research vessel Helios-9, eight light-years from home. The lights hum blue, and the ship's AI, MOTHER, watches every breath. On the last shift before stasis, Commander Hale is found dead in the airlock — space took him. But airlocks don't open themselves. Someone aboard did it. Perhaps without even knowing.
