The Three Investigators

#21 The Secret of the Haunted Mirror by M. V. Carey, 1974.

Mrs. Darnley has collected mirrors for years, and she has some pretty impressive ones in her collection. Her strangest mirror by far is the goblin mirror that her friend in another country, the Republic of Ruffino sent to her. There is a legend surrounding the mirror that says it was once owned by magician who used it to communicate with goblins under the earth. Supposedly, the magician went inside the mirror himself and now haunts it.

A man called Sr. Santora has been pestering Mrs. Darnley to sell the mirror to him, claiming he’s a descendant of the magician who created it. He insists that the legends about the mirror are true and that terrible things have happened to previous owners of the mirror. Mrs. Darnley didn’t believe these stories at first, but now, she and her grandchildren have seen this ghost in the mirror and heard unearthly laughter in the night. That isn’t the only strange phenomenon they’ve experienced. Someone tries to steal the mirror from Mrs. Darnley’s house, and Mrs. Darnley, not knowing what to do, asks the Three Investigators to find out what the mirror’s secret really is.

The Three Investigators are pretty sure from the beginning that someone is faking the ghost, although they don’t know exactly how. At first, they think that Sr. Santora hired the man who tried to steal the mirror, but when they follow the attempted thief, Pete sees him attack Sr. Santora!

Jupiter spends a stormy night at Mrs. Darnley’s house and has an encounter with the “ghost” that reveals how the haunting was accomplished and reveals connections to another magician who once owned Mrs. Darnley’s house and to the president of the Republic of Ruffino. It seems that the mirror contains secrets that aren’t entirely magical. There are two competing forces trying possess these secrets.

When Mrs. Darnley’s grandson is kidnapped, the kidnapper demands that she turn over the mirror in an abandoned warehouse. The Three Investigators must hurry to find the kidnapped grandson, discover which side in this power struggle is responsible for the kidnapping, and what the real secret of the mirror is before it’s too late!

The book is available to borrow and read for free online through Internet Archive (multiple copies).

My Reaction

The part I enjoyed the most about this mystery was the creepy legend and haunting of the mirror. One of the features of the Three Investigators books that I like is that they have some spooky mysteries in the pseudo-ghost story fashion of Scooby-Doo, and some of their supposed ghosts and supernatural creatures are much more original than in other series. The idea of a haunted goblin mirror and Jupiter’s encounter with it on a spooky, stormy night are delicious to a Scooby-Doo style mystery fan!

There are echoes of the first Three Investigators book in this one because there are secrets to Mrs. Darnley’s house that she doesn’t fully understand, and the haunting is based on magic tricks. There is some political intrigue to the story, too. The Republic of Ruffino isn’t a real place, so readers find out about its circumstances along with the Three Investigators. There is also a secret room and a clever hiding place for something in the solution to the mystery.
