The Frostbound Express

You are a private investigator hired to protect a sensitive diplomatic cargo aboard the Gilded Aurora, a luxury steam locomotive carving its way through the frozen peaks of the Northern Pass. What began as a tedious security detail quickly turns lethal when the train's lead engineer is found dead, his lungs filled with coal dust—but not from the furnace. Now, cut off from the outside world by a raging blizzard and severed telegraph lines, you must navigate a passenger list of high-society figures, desperate stowaways, and tight-lipped railway staff. Each carriage holds a new secret, and the biting cold outside is nothing compared to the chill of suspicion mounting within. The train is hurtling toward the mountain summit, and the killer is still on board. Can you piece together the conspiracy before the line runs out?
