The Jericho mountain race - five hundred miles of spongy desert sand and impossible rocks and mountain cliffs. It takes a special breed of man, riding a very special horse, to win that grueling contest. Colonel Robert Dinsmore knows he has the horse that can do it - Crusader, a magnificent black stallion. But he knows, too, that there's only one man who can ride that great horse - the wild outlaw Harry Camden. The Colonel enlists Harry to train and race Crusader, but Harry will not find winning the event an easy task. For there are those who hate Harry Camden a great deal, and love victory even more, and some of those men will stop at nothing to be victorious - not even murder!
