As John Farrow's Ice Lake opens, a corpse, shot through the neck, is found under the ice in a fishing hut on a frozen lake near Montreal. It's the dead of winter in a region that Farrow (a pseudonym for literary author Trevor Ferguson, whose critically acclaimed novels include The Fire Line) knows like the back of his hand: its back alleys and distant suburbs, its ethnic diversity and big city evil, the long black nights and searingly bright days of its unrelenting winters. He also reveals intimate knowledge of the diverse power groups that drive the novel's plot: the biker gangs, the Mohawk Warriors, the Mob, the bigwigs in the lucrative pharmaceutical industry looking to cash in on an AIDS cure, the various police forces with their petty animosities and territorial conflicts. Since the advent of Sherlock Holmes, though, most detective thrillers stand or fall on the qualities of their lead character. In Detective Émile Cinq-Mars (whom he introduced in the bestselling City of Ice), Ferguson has created a man of genuine emotions, highly ethical yet thoroughly practical, an old-style, straight-ahead cop. He doesn't leap tall buildings (or frozen lakes) in a single bound, but he knows how to keep digging in his own dogged style. A likable lead detective, a wintry ice maze of a plot, and a supporting cast of characters some of whom are patently vicious and others satisfyingly complex all make Ice Lake a captivating thriller. --Mark Frutkin
