From the wonderful The Hardy Boys book series written by Franklin W. Dixon and published by Grosset & Dunlap. This is book #30, 'The Wailing Siren Mystery'. It has the desirable 'blue binding' (turquoise blue), and is a hardcover edition without dust jacket (as sold). We believe this to be a 1960s edition of this book, and has a copyright date of 1951 and tan/brown/white pictorial inner cover pages. Book measures 5 1/16 x 7 5/8 inches. Please note that a former owner has written 4 lines on the first left white page after the printed inside cover pages, detailing his name, address and school grade (4th), which cover a bit over half this page lengthwise.

We actually are listing many others of these hard cover "blue binding" Hardy Boys books (including multiple copies of some books). The books appear to come from different editions of this set, based on slight differences in their covers. The books are all being sold separately; you can buy the one you need to complete your collection, or several to start one!

The condition of this #30 book is very good. It has been read or used and is not mint, but still in good shape. There is edge wear and corner bumping or wear on the outside covers, and other small dirt, wear spots or rubbing including slight dirt/darkening on the outer edge pages, but nothing bad or unexpected. The inside is nice and clean (with one wrinkled page at the top we saw). A highly usable, nice reading copy.
