Fly fisher, painter, and has-been private detective, Stranahan left a failed marriage and lackluster career to drive to Montana, where he lives in an art studio decorated with fly-tying feathers and mouse droppings. With more luck catching fish than clients, Stranahan is completely captivated when Southern siren Velvet Lafayette walks into his life, intent on hiring his services to find her missing brother. The clues lead Stranahan and Ettinger back to Montana's Big Business: fly fishing. Where there's money, there's bound to be crime.
