Nancy Drew Mystery Stories: The strange message in the parchment

Enhanced descriptions from Syndetics:

A sheep farmer receives a mysterious telephone call shortly after he buys a series of pictures painted on parchment. "Decipher the message in the parchment and right a great wrong," the voice says. Puzzled, the owner asks Nancy to help.

With Junie, his daughter, Nancy tracks down a kidnapper and a group of extortionists. Is there a connection between the message in the parchment and a boy artist on another farm? And who is responsible for the atmosphere of fear in the neighborhood? After several harrowing experiences, Nancy begins to tighten the net around a ruthless villain and calls on the assistance of her friends Ned, Burt, Dave, Bess and George to bring his nefarious scheme to a dead end.
