QUOTE : What is it about train travel that makes it such a suitable background for a mystery? Part of the answer surely lies in the enclosed nature of life on board a train—the restrictions of space make for a wonderfully atmospheric environment in which tensions can rise rapidly between a small ‘closed circle’ of murder suspects or characters engaged (as in the enjoyable old film <em>Sleeping Car to Trieste</em>) in a deadly game of cat and mouse. Similarly, a train journey may provide a mobile equivalent of the ‘locked room’ scenario beloved of crime writers and readers alike, as several clever stories in this anthology demonstrate.
