This is the second book in the Judy Bolton series, all of which were based on real-life incidents. It is well-written (far better than the Stratemeyer Syndicate's Nancy Drew), and the heroine is a likeable, down-to-earth young girl whose adventures brightened my childhood. I still enjoy reading them today!

Judy is introduced in the first book, The Vanishing Shadow. This is one of the best of the 38 book series and as with all Judy Bolton's teaches about loyalty, honesty, friendship. I would like to correct a previous review. Judy does indeed grow older, and marry, however she does not have a child. This was planned, however the series was not allowed to proceed to that point

I was introduced to both Judy and Nancy around 1948. I have always preferred Judy. I re-read several of both series lately, and am still of the same opinion. Nancy is an elitist, but likeable. Judy is a real person with good lessons about trust, honesty, making mistakes and correcting them. She embraces all types of people and encourages young people to not be afraid of differences.

Judy Bolton was my heroine in the 1960s. Unlike Nancy Drew, she comes from a believable background, and grows up with each story. The Vanishing Shadow combines personal values of honesty, trust and integrity with a gripping story line which has action and mystery, but no gory scenes or gratuitous violence.Although this story was written over 30 years ago, it has aged well. Suitable for pre-teens.
