This is probably the best of Tony Hillerman's fiction - much better than most of his Navajo Indian stories. In April 1975, at the time of the fall of Saigon, Moon Mathias learns that his recently deceased brother has a baby girl, still in Vietnam. Moon sets off on a journey to recover the girl, hoping that that the effort will prove impossible, thus reliving him of the need to proceed. Of course, Moon is a man of honor, who will make ever possible effort before quitting, and although things go from bad to worse, from failure to failure, he continues onward. In the end, he finds that he is not the man he believed himself to be, "a man who could be counted on to solve small problems," but that he is the man (Possibly Super Moon) that his brother thought him to be. Excellent read.
