A fun entry into the Doc Savage pulp series, this is another from the last part of the illustrious adventurer's published career, in which he was portrayed as a more normal, more fallible man. That's well and good, but unfortunately the author also was a bit fallible, pulling together all the plot points at the end a little too quickly and even forgetting to address the situation of the lone female character, a high-stakes gambler who might've made a good occasional foil/sidekick if that sort of thing would've been allowed back in the forties. Still, it was an enjoyable read, just not on a par with the best Doc Savage adventures.
