THE BERTRAMS (1859) by Anthony Trollope is an unusual novel of world travel, in addition to the typical subjects of matrimony and money, social strata, couples and relationships, by the author whose best-known work (such as the Barsetshire novels) is normally set in England.
This one has the flavor of a Middle Eastern travelogue with lively Victorian commentary and satire, and as such it is a fascinating glimpse into the international mindset of the time.
