So, I may or may not have mentioned this before, but I'm writing a book about Harry Houdini, and that means that I spend a few hours every day thinking about wonder. That is really what the book is about, more even than Houdini himself, it's about wonder: How can a man who died 90 years ago inspire wonder in an entirely different world? When Houdini died, movies were silent. Radio was new. There was no television. Superman had not been created yet, Winnie the Pooh only just.
