Some of this has stood the test of time; some of it has not. It’s unquestionably a product of the 1950s.

What struck me most, as a first-time Nancy Drew reader, was how suddenly the narrative jumps into the plot.

I also couldn’t help noticing that there’s a bit of product placement for other books in the series at the beginning (“Since solving [b:The Secret of the Old Clock|32979|The Secret of the Old Clock (Nancy Drew Mystery Stories, #1)|Carolyn Keene|https://images.gr-assets.com/books/1351534678s/32979.jpg|151480], she had longed for another case”) and a bit anachronistically at the end: “Although she was glad it was all over, she could not help but look forward to another mystery to solve. One soon came her way when, quite accidentally, she found herself involved in [b:The Bungalow Mystery|156979|The Bungalow Mystery (Nancy Drew Mystery Stories, #3)|Carolyn Keene|https://images.gr-assets.com/books/1351535987s/156979.jpg|151491].”

But there’s no product placement elsewhere, falling (to my modern eyes) short on detail. Nancy drives “her blue convertible”. Was it a Thunderbird or an Impala? Yet another mystery for an attractive blonde teen-ager to solve with her attractive friend.
