This is number 8 in the Hardy Boys Book series written by Franklin W. Dixon. It was copyrighted by Grosset & Dunlap in 1969 and is part of the blue cover series. It chronicles one of the Hardy Boys wonderful mystery adventures.
The book is in very good condition with some rubbing to the edge and corners of the covers. The interior of the book is in great condition. It looks unused. There is an inscription on the first blank page dated 1974.
If you are looking for a particular Hardy Boys book that I do not have on my shop please let me know. I have quite a nice inventory right now.
I will be happy to combine purchases to save on shipping costs. International orders are always welcome.
