A hard fall took hotshot jockey Sid Halley out of the horse racing game, leaving him with a crippled hand, a broken heart, and the desperate need for a new job. Now he's landed a position with a detective agency, only to catch a bullet from some penny-ante thug. And things are about to get even more hectic—the agency is giving him a case to handle on his own. The case brings him to the door of Zanna Martin, a woman who might be just what Sid needs to get him back up and running. But he's up against a field of thoroughbred criminals, and the odds against him are making it a long shot that he'll even survive . . .
