Ruth Fielding at the War Front is a nice little piece of propaganda. Stratemeyer’s perfect American boys and girls all had to do their duty by their country when the U.S. entered WWI, of course, so in this book, Ruth is working for the Red Cross, Tom is a lieutenant in the army, and Helen is doing something or other in Paris. I would probably know what, specifically, if I’d read Ruth Fielding in the Red Cross, the book before this one. Anyway, Helen is out of the picture for most of this one.
