Siesta short, genteelly articulated and scantily plotted -- this deals with a gracious Senora and the good Father Rodriguez who lives next door where a dead man is found, and Henry Cooper of the Embassy and his warm water romance with a young girl, and primarily with an archaeologist, Dr. Hartung, searching for Cortes' treasure and coming up with a smashing find overlooked by others more interested in the native product. . . . Pleasant and pretty and painless.
