The story opens with a bombing on Wall Street, leading to the deaths of five men. One hour later a similar bombing takes place at Grand Central Station, followed by a third explosion at the subway entrance at Columbus Circle. What is going on? Sounds like a case for The Shadow…
The Shadow, as usual, needs help gathering all the evidence and clues necessary to expose the entire plan and who’s behind it. Several of his regular agents contribute to this adventure, including Harry Vincent who has been in all seven of the novels before this one. Also, contact man Burbank is here, as well as reporter Clyde Burke. Detective Joe Cardona plays a large part in this story and I understand he appears in over 200 of the pulp novels. The Shadow, himself, appears in disguise as Henry Arnaud for the very first time although not quite the same Arnaud that will appear in later stories. The Arnaud disguise reportedly appears in twenty-eight of The Shadow's adventures, but usually Arnaud was a solemn businessman. This time around, he is an eccentric multi-millionaire.
This was a fast-paced adventure with a lot of moving parts. The identity of “The Black Master”, the one behind the bombings is fairly evident from near the beginning but it is still fun to watch how The Shadow and his agents figure it out.
