I should probably wait to write this because there are five stories in this book and I've only read the first two, but, first, I think I have the flavor of the work, and, second, this sort of thing is best in small doses spaced over a long period of time. I expect I will get to the others one at a time when the mood strikes me. Delightfully clunky writing, with over the top caricatures, and long, adjective and adverb laden run-on sentences that have to be seen to be believed --but it's fun! Action paced, somewhat discombobulated adventure stories where midway through the evil sky-pirates capture the zeppelin, leaving our hero in a bind, to say the least, and five pages later after a couple fistfights, a clevery ploy and a failed romance, our hero now finds himself running through a south sea jungle pursued by hungry cannibals pulling the professor's daughter by the hand as he goes (of course, she does not yet love him, but she is, of course, suffering under the lies the sky-pirates told her after he hid his true identity so that he could later foil their plans.) It's tough to rate this, and to be honest at times I found the writing style and convoluted action a bit confusing, and had to turn back a page and start over, but if you are looking for a collection of real, 1930s, thrilling, unpolished, hack-pulp fiction involving zeppelins then this is exactly what you'll get in this volume.
