Query: Wonderful biography

Chernow's Alexander Hamilton is a wonderfully written and narrated biography; sometimes as personal and compelling as fiction. It's long and detailed, but my interest never lagged. I felt surprised at the mysteries surrounding the fatal duel; Chernow speculates between two extremes: that Hamilton may have felt depressed and resigned to death, or that he may have expected a harmless ritual in the routine defense of honor. Other than that loose end, for which there may be no definitive answer, I thoroughly enjoyed listening to this book and learning about the man who had such a great hand in shaping the government of the new United States.
