It might very well be that the wild horse of the Mongolian plains, ancestor of today's horses, would make a good subject for a juvenile novel. This one however, is fenced in by an overpopulated plot that makes use of a real setting in a fantastic way. 14-year-old Jebby Stuart falls in love with a caged wild mare at the Washington National Zoo. A kilted old Scotsman, a Dorje Lama, senators, some juvenile delinquents (who hate Jebby for being so polite) and even some zoo officials turn up in the story. It's an extraordinary way to run a zoo, but they're all on hand there after midnite in a final scene that has Jebby protecting the mare from the j.d.'s and helping their leader to repent in an unbelievably articulate and self analytical on-the-spot confession.
