Holland begins with the duel's origins in the trial by combat, and moves deftly through the centuries (from fencing masters in Italy to swordfighting in France to dueling pistols in England to bloody frontier affairs in the American West, with stops in between in Ireland, the American South, Russia, and Germany, among other places). Given the breadth of the subject matter (dueling was an accepted custom in many cultures, and although it was deplored and illegal at various times, laws against it were very often not enforced), Holland doesn't quite treat the subject exhaustively, but her digressions make this well worth reading. There's plenty of information on how honor was treated (as the currency of polite society), how exactly a duel should be arranged (by the seconds, via a series of notes), the insults most likely to bring about a challenge ("liar" is the most unforgivable, right up with physical violence, which either requires a challenge or renders the aggressor beneath contempt, depending on the culture), and the capabilities of the weapons involved (smoothbore pistols weren't particularly accurate).
There's a lot here, but Holland is most entertaining in her snapshot-like depictions of the many duels, spotlighting combats across countries and centuries. Her eye is sharp, and her wit is acerbic. Highly recommended, it's a quick and entertaining read.
