I was given this book a few years ago and finally got around to reading it. A must read. It's about a little rich girl who rides around in a roadster, has servants, and solves mysteries. A pretty normal 16 year old girl during the depression. This is number 4 in the series and was written by Mildred A. Wirt Benson.

Nancy Drew

The original Nancys were full of descriptive imagery and flow, suspense and drama, and more vividly brought to life the character of Nancy as opposed to the faster paced and less descriptive flow of the revisions. Most of the originals were the work of Mildred A. Wirt Benson, who wrote 23 of the first 30 books--1-7, 11-25, and 30. Tired of what she liked to call the "namby-pamby" style of girls' series books, she had no intention of characterizing Nancy as namby-pamby. Nancy came to embody the feisty spirit of independence that emanated from Mildred. Mildred always felt that girls could do the same things as boys could and she lived her life that way. It was her take on Nancy that helped spark Nancy's widespread popularity. Her ideas of what Nancy should be were different from the more traditional finishing-girl style of Harriet Adams, and as the series went on. As a result of these differences, Nancy underwent changes at the direction of Harriet and later under Harriet's revision.

You could get a new copy but go for an old one. And it looks like those written by Mildred A. Wirt Benson are the classics and these were rewritten in the 1950s to make them more modern.
