Meurtre A Grande Vitesse (F) (1985) - Amstrad CPC - Adventure, Mystery.

The events take place aboard a TGV train - France's high-speed rail transport - running between Paris and Lyon. A high-ranking senator Albert Pérignac is found dead in one of the railway wagons - and as a private detective who happened to be onboard as well, you are entitled to solve the mystery before the train reaches its destination. Was it an accident, a suicide - or a murder, perhaps a political one?
