Summary
When Nancy Drew receives a valuable moonstone as a gift from an unknown person, she is amazed and puzzled. But it is only the first of several startling events in this complex mystery that challenge the ingenuity of the pretty sleuth.
Why are the Bowens - a missionary couple who recently returned to the United States - having so much trouble finding their missing seventeen-year-old granddaughter, Joanie Horton? Nancy and her friends travel to Deep River, the town where the young Jonie lived. From the motel where Nancy and her friends stay, they can see an intriguing castlelike structure with a drawbridge. Gossipy Mrs. Hemstead at the village tearoom insists that Moonstone Castle is haunted. Curious, the three girls attempt to explore the abandoned castle, but an ominous voice warns them away.
Other strange happenings in Deep River convince Nancy that there is a connection between Moonstone Castle and the mysterious moonstone gift. But what is the significance? And where does the baffling disappearance of Joanie Horton fit into the intricate puzzle?
Carolyn Keene was the pseudonym that Mildred Wirt Benson and Walter Karig used to write Nancy Drew books. The idea of Nancy Drew came from Edward Stratemeyer in 1929. He also had other series, that included the Hardy Boys, but he died in 1930 before the Nancy Drew series became famous. His daughters, Harriet and Edna, inherited his company and maintained Nancy Drew having Mildred Wirt Benson, the original Carolyn Keene, as the principal ghostwriter. During the Depression, they asked Benson to take a pay cut and she refused, which is when Karig wrote the books.
Karig's Nancy Drew books were Nancy's Mysterious Letter, The Sign of the Twisted Candles, and Password to Larkspur Lane. He was fired from writing more books because of his refusal to honor the request that he keep his work as Carolyn Keene a secret. He allowed the Library of Congress to learn of his authorship and his name appeared on their catalog cards. Afterwards, they rehired Benson and she wrote until her last Nancy Drew book (#30) was written in 1953, Clue of the Velvet Mask.
Harriet and Edna Stratemeyer also contributed to the Nancy Drew series. Edna wrote plot outlines for several of the early books and Harriet, who claimed to be the sole author, had actually outlined and edited nearly all the volumes written by Benson. The Stratemeyer Syndicate had begun to make its writers sign contracts that prohibited them from claiming any credit for their works, but Benson never denied her writing books for the series.
After Harriet's death in 1982, Simon and Schuster became the owners of the Stratemeyer Syndicate properties and in 1994, publicly recognized Benson for her work at a Nancy Drew conference at her alma mater, the University of Iowa. Now, Nancy Drew has several ghostwriters and artists that have contributed to her more recent incarnations.
