My reasoning was simple. What puts people on edge? The answer: crazy people. Think about it. Imagine you’re on a quiet train trying to read, say, Ian Fleming’s From Russia With Love. The gentle lurch of the the carriage is the perfect setting to read of Bond’s escape from Turkey on board the Orient Express. Just as it dawns on you that this is the second Bond novel in which Bond falls in love with a woman described as a man, the train pulls into a station on gets a crazy person.
