Murder on the Mars Express

The silence aboard the Prometheus is broken by an emergency klaxon—Dr. Yuki Tanaka, renowned xenobiologist, has been found dead in her private quarters, her body twisted in the unmistakable agony of vacuum exposure. But how could this happen in a pressurized cabin, light-years from the nearest port? The scene tells a chilling story: a broken access card reader hangs from the wall, its casing pried open with disturbing precision. Near her bed, a coffee cup lies on its side, dark residue pooling beneath it. The body's position suggests she collapsed suddenly, reaching for something—or someone—in her final moments.

Five individuals had access to this section of the ship during the critical window: Felix, her fellow researcher; Captain Reed, who commanded the vessel; Doc Chen, the ship's medical officer; Kai, the young engineer; and Anya, a passenger with unclear motives. Each has their own story, their own alibi, their own secrets. The recycled air carries whispers of rivalry, hidden connections, and desperate conversations in the observation deck. Someone aboard the Prometheus is a killer, and the evidence is as cold as the void outside. Can you piece together the truth before the ship reaches Europa Station?
