Asesinato en el Orient Express 1986

A murder has happened on the Orient Express train. There are 12 characters, the suspects. One player moves the characters around a map of Europe, and he is the only one to know the identity of the killer. Each of the other players leads a team of 3 detectives around Europe, accomplishing missions that give them clues about the killer's identity, while the killer tries to mislead them. The detective teams must cooperate, but remembering that only one player will be the winner. If the killer has not been discovered after the set time limit (between 1 and 2 hours), he wins.
