Three men and a woman share a train compartment between Edinburgh and London. From different age groups, backgrounds, and even countries, they prove it is sometimes easier to bare your soul to strangers, except for one coveted secret of an old love that is revealed only to readers. The travelers share their personal or family love stories and, oddly enough, they all involve trains. Diverse anecdotes take the reader all over England, Scotland, Australia, and the eastern part of the U.S., past and present day. The stories of Trains & Lovers get at the heart of human emotions. By the last chapter, Alexander McCall Smith may convince you to book a rail journey.
