I've read "The Edge" at least a dozen times since it was published and my enjoyment never diminishes. The lead character, Tor Kelsey, is full of charm, wit, and plenty of humility -- his self-effacing ways lead one to wonder how it is he doesn't realize his own attractive nature. The romantic relationship in this book was one of the most realistic ones Mr. Francis has ever written, possibly because the two involved spend enough time together to develop a real rapport (unlike some of his other "romances", where the man and woman meet and suddenly have deep feelings for one another). While "The Edge" is less of a mystery than other books -- we know Julius Apollo Filmer's a bad guy from the start -- the characters are incredibly well-written and the book becomes more about seeing why Filmer does what he does and how he's going to get caught. The Lorrimore family especially was very well-crafted, from the needy and petulant daughter Xanthe to screwed-up teenage son Sheridan to the "money can't buy you everything" father Mercer. On top of everything else, Mr. Francis captures the beauty of the Canadian Rockies and the excitement of traveling by train. I know that before I die I will have to take a train trip across Canada, and that's due to this book.
