Your the investigator to a scene involving a dead body. All you know is the man has been found with a round trip train ticket into the city, and upon leaving the city at the end of the day, he was found with a gunshot wound to the head and a gun in his hand.
In the interest of keeping the game a situation of deduction and reasoning, I will ask that multiple questions not be used. It's too easy for someone to just ask many randon questions and get lucky, and that is not the point of the game. The goal is to isolate who he was, why he was on the train, why he shot himself, etc., through rationale and questions based on elimination of possibilities.
And if you know the answer because you played this before, please let others figure it out.
Good Luck... :-D
