"Those Who Walk Away" is a concise, fast reading novel of low-keyed suspense. The background is an appropriately gloomy wintertime Venice. Ray, the key character, has lost his wife to suicide. Ed is the unforgiving, not to mention self-centered, father in law who blames Ray for his daughter's death and tries to kill him. Ray pursues Ed through the canals, back streets, cafes, gondola rides and fancy hotels of Venice to clear his conscience and calm Ed down. The embittered Ed has none of this and chases Ray in the same fashion. Both find atmospheric Venetian "hiding places". To use a movie term, Highsmith makes use of an excellent supporting cast: Signor Ciardi, Inez, Luigi the gondolier and Elisabetta almost steal the show from the main characters. Highsmith also pulls the reader into the plot quickly, a talent of hers. We are involved from page one! The ending, which no reviewer should reveal, is smooth and satisfying. To fully enjoy the tale, the reader must surrender credibility on 2 points: 1) Those "meetings" between Ed and Ray are truly coincidental and 2) The Venetian police, as personified by Detective Dell'Isola, ask few questions and press few charges. I would give the author her license on those points and enjoy "TWWA" on its own merits. A closing question: Did Ray really let a nice Italian girl like Elisabetta get away? Did he ever go back to Venice to see her just once more?
