Abroad with the Jimmies

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.
