The Secret of Shadow Ranch (Nancy Drew Mystery Stories, #5)

Nancy Drew is in Arizona. She's been invited to spend a short vacation at Shadow Ranch which is outside Phoenix. She soon discovers that it's having problems. A phantom horse has been seen racing through the nearby meadows, and there's been malicious damage to the buildings and fences. Could it all relate to a treasure hidden somewhere on the ranch by that 19th century outlaw, Dirk Valentine?
