The Three Investigators

#1 The Secret of Terror Castle by Robert Arthur, 1964, 1992.

In the first book in the series, Jupiter, Pete, and Bob form the Three Investigators, an organization dedicated to solving all kinds of mysteries.  It was particularly Jupiter’s idea. They have been friends for a long time, and they used to have a club dedicated to solving puzzles. Now, they’ve decided that they want to solve more complicated problems and mysteries. Jupiter has won the use of a Rolls Royce and chauffeur for a month by entering a contest at an auto rental agency, so he thinks that it would be a good time to get started because they will have transportation to anywhere in the city.

Jupiter also has an idea for their first case, something that will help them get publicity for their new investigative organization. There is a rumor that a director, Reginald Clarke, is looking for a genuine haunted house to be the setting of his next movie. Jupiter manages, through some clever trickery, to get an interview with Reginald Clarke and persuades him to introduce this account of their first case if he and the other investigators can find a genuine haunted house right in town. Clarke takes them up on it, not because he thinks they will succeed, but because he sees it as the only way to get Jupiter to stop doing an unflattering impersonation of him.

Jupiter, however, is confident that they will be successful because he already knows the perfect place to investigate. Terror Castle is a large mansion that was built years ago by an old actor who was in silent films. All of his movies were scary ones, and since his death under mysterious circumstances, no one has succeeded in staying in the castle very long. Strange apparitions have been seen there, and anyone who tries to spend the night there is overcome by inexplicable terror. As far as Jupiter is concerned, all they have to do is prove that the castle is really haunted, and that means that the Three Investigators must visit it themselves.

In the original books, the director that Jupiter tries to find a real haunted location for was Alfred Hitchcock.  Alfred Hitchcock introduced the early books in the series and played minor roles in some of them, and The Three Investigators capitalized on his reputation.  When the series was re-released, however, Alfred Hitchcock was replaced by a fictional director, and his role in later books was taken by a fictional mystery author named Hector Sebastian.  In the re-released version of the first book, Reginald Clarke refers the boys to Hector Sebastian at the end of the story so they can help a friend of his to find his missing parrot, which leads directly into the subject of the next book.

The haunting in this story (as with others in the series) has a reasonable explanation, not a supernatural one.  In fact, one of the things that I always found memorable about this book was the explanation of how the inexplicable feelings of terror people experienced were created using sound waves which could be felt but which were beyond the normal range of human hearing.  I’m not sure whether the book was completely correct about the science behind this technique, but I have heard about sounds being used to create odd or even harmful effects on human beings in real life.  As for the reasons behind the haunting, they concern the original owner of the castle and the life he lived.

This is one of the books in the series which was made into a movie, The Three Investigators and the Secret of Terror Castle, but the movie was very different from the original book.  In the movie, the owner of the castle was an inventor, not an actor.  Part of the plot also concerned Jupiter’s deceased parents and a mystery that they had been investigating.  Jupiter’s parents were not part of the original book at all.  A villain who appears in some of the other books in the series also makes an appearance in the movie, although he had nothing to do with this particular story in the original series.  Overall, I don’t recommend the movie for fans of the original series.  The changes don’t seem to be for the better, and I think people who remember how the original story was and liked it would be disappointed in the movie.

There are multiple copies of this book available to borrow for free online through Internet Archive, both the original version with Alfred Hitchcock and the updated one.
