"Celine" by Peter Heller
In Celine, Peter Heller creates one of the most unusual characters in mystery writing in recent years. A 68-year-old eccentric member of the WASP elite, P. I. Celine investigates the decades-old disappearance of a National Geographic photographer in Yellowstone National Park. Reading more like general fiction than focused mystery genre, the wide range of writing veers across the protagonist's own background and family relationships, East Coast and Western settings, socio-cultural history, and political intrigue.
