I'm pretty sure that everyone on the train except for me is a cleverly-diguised secret agent for the CIA, Her Majesty's Secret Service or some other such agency. I wish I could crack the secret code they use to discuss the important details of their important cases, but they do an amazing job of using this ingenious code. Everything they say sounds like they're discussing mundane details of boring, frustrated lives. The talk is all about husbands and wives and annoying coworkers. They discuss political problems in church committees or personal slights by in-laws. To the uninitiated, like me, it's impossible to see all the fascinating issues of international importance that are hidden in these conversations. They must be terribly important, however, for so many to have gone to such lengths to mask them so very, very well.
