Enigmas - Floyd Merrell - Bog

Four couples from the southwest search for Spanish treasure in northern Mexico. They meet strangers from another world dwelling within four dimensions, Tarahumara people with a magical philosophy of life, local bandits, narcos, sus-picious police and military personnel. Yet, they become enchanted by the vast Sierra Madre, find treasures exceeding their wildest dreams, begin squabbling over the take, until the alien visitors sequester most of it. Back home, they make amends, but soon realize their bizarre adventure will haunt them to the end.
