Do the following two things appeal to you? A holiday in Venice, away from the tourist traps, investigating the city's more unusual nooks and crannies? Or trying (by proxy) to solve a particularly mystifying crime case with a variety of intriguing suspects? Well, you don't need either the money the first would require or the police qualifications the latter might need, if you merely shell out the modest outlay for Donna Leon's Through a Glass Darkly, the latest in her … mehralways assured Commissario Brunetti novels. Admirers of these books need no recommendation: they have been amazingly consistent in their development over the years, and have rarely slipped into the overfamiliar--there's no sense that Donna Leon is tired of either Brunetti or his battles with municipal and governmental corruption. It's spring in Venice, and Commissario Brunetti and his associate Vianello undertake a task not officially sanctioned by the Questura--they will try to do what they can for Vianellos friend Marco, an eco-activist who has been arrested after an environmental protest turns ugly. Soon after, Brunetti witnesses the almost psychotic enmity of Marco's father-in-law, who almost seems prepared to murder his relative (a fear that Marco's wife shares). The old man's glass factory on Murano, the source of the conflict between father and son-in-law, becomes the scene for a murder: in front of the furnaces which eternally burn at high temperatures, a body is found and Brunettis search for the killer is aided by clues found in a volume of Dante. All of the customary Leon fingerprints are satisfyingly in place here: the sultry and immensely vivid evocation of Venice; the ever-present pall of evil and corruption that suffuses the beauty of the city, and (most pleasurably of all) the careful delineation of character in Brunetti and his associates. This is a series that has a long time to run yet.--Barry Forshaw weniger
