One of these books where you wonder why you have never heard of any part of the story: the Chicago Columbian Exposition (World Expo, we would call it today, I guess) is one of the more forgotten ones outside the US. The mass murders of one Mr Holmes (the most frequently used name, there were others) must also have gotten lost under more illustrious cases such as those by Jack the Ripper or the more recent ones. But the book, let's give it that, manages to convey the feeling for the bigness and also in a way the greatness of both events. The way America was expecting something that would cast a shadow over the glorious Paris World Expo and its Eiffel Tower, the way American cities tried everything they could, at the same time, to keep each other from getting the deal, the jealousy among the architects and the ridiculous elephantiasis of committees and administration that almost kept the fair from happening. If you step back a bit and look at the issue from the distance, you will not see anything that would be very extraordinary in the course of preparation for such a huge event. Setbacks and small catastrophes. Casualties and missed deadlines. Spectacular innovations (Ferris Wheel) and incredulity towards its realisation. Erik Larson manages to draw you inside, however, and allows you to get a feeling for the huge task at hand, how unlikely it appears that one person (Burnham, the chief architect) should bear this responsibility. The psycopathic killer story, in contrast to that, sounds too much like a thing out of an Amazon bestseller list thriller, it never evokes the same feeling of realism, of being near. You somehow expect a more tense storyline there, with an elaborate detective character chasing the beast and hunting it down - but this expectation is disappointed, because in reality, things don't usually work out that way... It can be argued that the book had been more intense, more straightforward, more thrilling, had it restricted itself to the White City. As it is, the book is a bit too long for comfort, but an interesting read nonetheless.
