Query: A Non-Fiction Tale of Two Cities

Larson captures the best and worst of mankind. Two bigger than life men, Daniel Burnham and H.H.Holmes set about creating beauty or destroying life on grand scales. Both were successful and both had setbacks.Burnham was the visionary who was largely responsible for the success of the 1893 Chicago Worlds' Fair, commemorating the 400th anniversary of Columbus' discovery of the New World. Holmes took advantage of (mostly) vulnerable women who made their way to Chicago on their own, killing them when he tired of them.The story of the fair or of the slaughters would have been interesting books on their own. Weaving the tales took away from the story of the fair. While the fair was the background that enabled Holmes to have his pick from thousands of potential subjects, the detail of the how the fair developed didn't add to the story of the slaughters.Larson is a good writer, but I would have preferred that he wrote two separate books.
