The Royal Limited: Murder On Board

From BoardGameGeek:

A stormy night. An isolated train traveling through the English countryside. It's the perfect spot for a heinous crime. But the killer didn't account for a renowned detective on board... This 3-card expansion for The Royal Limited adds Detective, Victim, and Murderer cards along with some gameplay changes. What would a train be without a little murder mystery? In this 3-card expansion, you must find the victim and catch the killer before time runs out or lose the game. The player's goal is to, by the end of the game, have the detective find the victim and arrest the murderer. To do this, they will move the detective along the train and land on spaces with the assigned VIP. In addition to the normal scoring, both the victim and murderer cards must be flipped to green, or else you lose.
