This book may be a little hard to find, but it's definitely worth the effort for any fan of the Shadow. It's subtitled “The complete story behind the mysterious shadow of pulp magazine and radio fame compiled by his chief creator.”
The first chapter is Introducing the Shadow, which is about the history of the Shadow. It's filled with information and lots of the original illustrations from the stories. As part of this is a listing of the Shadow pulp novels.
The second chapter is a very interesting one about how Walter B. Gibson actually wrote the Shadow novels, the most interesting part being about how he outlined his work in advance.
The third chapter is about “Evolution as portrayed in the covers of the magazine,” complete with a lot of black-and-white illustrations. This is followed by a chapter showing some of the covers in color.
The next chapter is about the Shadow and his agents, again with some of the original illustrations of the agents. This is followed by a chapter on Illustrating the Shadow. Then, there's an original short Shadow story entitled “The Riddle of the Rangoon Ruby.”
Next is a chapter about the radio version of the Shadow, and then some illustrations of some pages from a Shadow comic, followed by a listing of the Shadow radio episodes. This is then followed by a chapter on Writing for the radio episodes and includes the script to the Death House Rescue episode.
The Shadow on the Silver Screen is covered next, and then there's a chapter on the Shadow comics, then on on the Shadow comic strip with a number of the original strips being included.
Next is a chapter on various codes found in Shadow stories, and then a chapter about codes on some of the covers of the Shadow pulps. Rings and Things for the Shadow Collector is next, and then a short section on Gibson himself.
As can be seen, there is a lot of good material in this book.
