Adventures on the Trans-Siberian Express, by Robert M. Goldstein: Two days aboard what he believes is the Trans-Siberian Express, the author discovers he’s on the wrong train. It is 1987, and he is traveling in the Soviet Union, holding a train ticket that mistakenly identifies him as a Finn. In fact, he is a short, swarthy Mexican-American-Russian-Jew, who speaks only enough Russian to proclaim that he is Bob, the tourist from America. 
As the trip unfolds, what begins as the fulfillment of a childhood dream becomes a journey with a cast of characters worthy of a Russian novel. A grim old woman takes his only pair of shoes. Mr. K., a tour director in Novosibirsk, is shocked when an actual tourist turns up during the middle of an ice storm. A beautiful Russian woman rescues the author from disaster in one city, only to mysteriously reappear in another, fueling his growing paranoia that she is a KGB agent. 
Throughout the story, Goldstein interjects historical anecdotes.
