Vintage Mystery Reading Challenge 2013. It does not say children's books aren't allowed. So I hope it's acceptable. It was originally published in 1959. The category is: 15. Cops & Robbers: a book that features a theft rather than murder. This book will work for a bunch of other challenges as well!
The Story: Nancy is in a helicopter over River Heights. She asks to fly over her house. The pilot says it's not allowed but she can look through some binoculars and see the house. She does and there is someone breaking into a window on the second floor. The pilot calls the police but they did not get to the house in time. There have been some other break-ins in town. A mystery for Nancy to solve!
Nancy gets asked by a client of her father's, Mr. Sakamaki, to help with a puzzle left to him by his grandfather. He has some symbols he cannot decipher. He needs to figure this puzzle out before he can inherit an estate in Hawaii. Of course, Nancy and her girls, Bess and George, along with Mrs. Gruen go to Hawaii. The boys are also going to Hawaii with a group. Big Surprise! The two mysteries are intertwined and Nancy saves the day by figuring everything out as usual.
This book reminded me of how easy it is to get information these days. Nancy could have solved the mysteries from her room with a computer!
