This is a romance story book. The 'Jimmies' are an American married couple, and those who go with them on this journey of odd adventures are the narrator and her married sister, Bee, who left her husband and child at home, and seems to have forgotten them, judging from her attentions to a duke and to certain fine looking German officers. The women enjoy themselves vastly, and the man by yielding everything gets through alive, which is perhaps all he ought to have expected. It speaks volumes for an amiability I have always claimed for myself through sundry fierce disputes on the subject with my sister, that, even after two years of travel in Europe with her and Mr. and Mrs. Jimmie, they should still wish for my company for a journey across France and Germany to Russia. Bee says it speaks volumes for the tempers of the Jimmies, but then Bee is my sister, or to put it more properly, I am Bee’s sister, and what woman is a heroine to her own sister?
