Featured on pages 106-108 is information on boy and girl detectives: the Syndicate and Nancy Drew and the Hardy Boys. Pictured is the Applewood book cover of The Secret of the Old Clock.
For Drew enthusiasts who like to collect anything that has something to do with Nancy Drew this is for you--and if you like mystery in books, tv, etc.. this will be a nice feature on the history of this genre--makes a nice coffee table book too. Copyright 2001, Collectors Press.
If you don't have a Half Price Books, I've seen this listed often on eBay and also many copies abound at Amazon.com.
