The contemporary western mystery series follows the further adventures of a half Indian cattle inspector and "character of legendary proportions" (Ridley Pearson).   Officially, Gabriel Du Pré is the cattle inspector for Toussaint, Montana, responsible for making sure no one tries to sell cattle branded by another ranch. Unofficially, he is responsible for much more than cows' backsides. The barren country around Toussaint is too vast for the town's small police force, and so, when needed, this hard-nosed Métis Indian lends a hand. In Gabriel Du Pré, "Bowen has taken the antihero of Hemingway and Hammett and brought him up to date . . . a fresh, memorable character" (The New York Times Book Review).   The Stick Game: After a Native American boy turns up dead, Du Pré takes on a mining company that's poisoning reservation children. Is there something more sinister than greed and indifference at work?   "Wonderful . . . wise." --The Washington Post Book World   Cruzatte and Maria: While reluctantly serving as a consultant for a documentary about Lewis and Clark's expedition up the Missouri River, Du Pré stumbles upon a national treasure: Meriwether Lewis's lost journals. Then members of the film crew start dying . . .   "A solid entry in a great series." --Booklist   Ash Child: In the midst of a drought in Toussaint, Montana, brushfires, meth dealers, and murder challenge the Métis Indian tracker and cattle investigator.   "Compelling . . . plenty of action . . . a pleasure to read." --Publishers Weekly
