To be honest, I couldn't finish this story. The dialogue is very stilted - even for this era of fiction. The story was going along pretty well, but the dialogue was just too painful to continue. The plot seemed to move along is clearly manufactured jumps from scene to scene.
Pretty good story. It moves along well and contains a lot of action, well written dialogue, and a logical plot. The twists and turns logically lead from place to place and plot turn to plot turn. I think it's supposed to take place around the 1940s or 1950s and the writer clearly isn't much for prediction in technology, but hits surprisingly close in some political themes. There's an exciting dirigible battle in the Asian theater well described and the rise of the Asian empires against the west is also clearly nailed. I found this book to be just as entertaining than any contemporary novel.
Interesting twists in the plot, with a surprising (although somewhat unlikely) method of murder. The police investigation of this crime is especially interesting in like of current television shows like C.S.I. and Law and Order. It is easy to picture the folks in this story as straw-hat wearing, upper class, gentlemen and ladies taking their turn around a society of private aeroplanes, country clubs and long hooded Phaetons with wire wheels and big headlights. Pretty enjoyable all-in-all old man.
Pretty good detective novel about the Pinkertons following up a train robbery. It struck me as being pretty logical in plot and enjoyable in pace. Nice pre-auto setting written in a workmanlike way.
