You are entering a train car that has just left the station.

It turned out that you were not traveling alone - a man in a black leather jacket was sitting opposite the window on the lower tier, reading a book. On his luggage you could read the name - "Jack Kaminsky". A man hears how you opened the door and he immediately hid something very quickly in a briefcase - you did not have time to see it, but at first it even seemed to you that it was a gun...

No , how stupid, it can't be a gun
