Wow, almost 60 years have passed since I read Nancy Drew, so I spent a day revisiting Nancy and her gang of ghost busters. The Invisible Intruder contains five cases that Nancy and her friends must research and aid the police and assist the landowners in stopping ghost rumors. I thought that this would be a simple reading, but seashells entered into the various jaunts and a thorough description of seashell collecting transpired. I had forgotten the forceful nature of Nancy and her bossy attitude. She runs amok so many times and throws caution to the wind. Luckily for Nancy that her group of friends rescue her from serious consequences. Again, a very enjoyable read that does not contain killing and graphic violence.
Carolyn Keene never fails to deliver an excellent mystery novel in her series of Nancy Drew, super sleuth. I really like how all of her novels follow the same pattern, one would think this could be boring, however, it is satisfying to the reader to know or be able to guess at the events of the novel.
Nancy Drew remains, as always, a terrific protagonist. Her friends, Bess and George, are terrific "sidekicks" with well-developed personalities. I never fail to enjoy these novels, keep producing them!

I absolutely loved Nancy Drew growing up. This was a series I latched on to for dear life and never let go. Anytime my mom and I would go to antique stores, we'd peruse the Nancy Drews and add them to the collection (oftentimes my mom had to make deals with me on how many I could buy). So, while I don't remember the exact details of each and every one, the entire series was amazing and really fed my love for reading (especially novels full of suspense and mystery). Thank you, Carolyn Keene, for giving us an intelligent female character to fall in love with in Nancy Drew!
Nancy and a whole group of her friends are determined to solve a series of ghost mysteries, all of which have appeared suddenly in the same geographic vicinity. They find a tie between the mysteries, and attempts to buy pieces of property at far below their value (a common Nancy Drew theme). It seems that someone with a lot of technical skill has been rigging up a series of "ghosts" and using them to scare people, along with stealing a variety of valuable shells for resale. As Nancy and her friends attempt to evade danger from bombs and fireworks, they rush to track down a gang of increasingly slippery crooks.
This book is about a girl detective who's name is Nancy Drew.

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 show more 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. (Bowker Author Biography) show less
