Book two in the RM Outdoor Adventure Mystery series by Agatha Award finalist Beth Groundwater.

Fly fishing is dangerous? River ranger Mandy Tanner had no idea until days before a huge tournament in Salida, Colorado. True, the Arkansas River can be a man-eater, but the rapids weren't responsible for driving a hatchet into the neck of would-be competitor Howie Abbott—a secretive man who may have been cheating. While casting about for suspects, Mandy seeks clues from Abbott's family members, including her best friend, bartender Cynthia Abbott. But when Cynthia becomes the prime suspect, Mandy realizes that trolling for the true killer has plunged her way too deep into wicked eddies.
