Everyone's a Suspect

Tadashi Hamada, worlds greatest detective. He is on a train with a group of people who are all guilty of something. Weather it be the the heiress with a hidden past, or the widow that claims that the cause of her husband's death was mysteriously undetermined.
Or the shy, yet aggressive girl who was conveniently always in the right place at the right time. Or the new professor who seemingly "lost" all of his students. Or maybe even the charming businessman who was disowned by his first class family under mysterious circumstances.

But when a sweet village girl from Central America is murdered on the first night of the train ride, things start to get even fishier. Detective Hamada must find a way to determine who the murder is before he himself is killed, along with everyone else on the train.
