John Julius Norwich is an earnest and somewhat stiff-backed editor. So it's not entirely surprising that he reveals in his introduction that he is "braced for objections" over his selections for "The Great Cities in History," a collection of essays and images.

It's a dull question, and Norwich answers it dully, by pointing to the "in history" part of the book's title. The better answer would have been that there's not a shred of romance in Toronto and Melbourne....
