The facts are that I am not responsible, I was sane enough up to the day that I decided to publish this book and have been since; but on that particular day I was taken possession of by an unseen power--a Chicago publisher-who filled my alleged mind with the belief that the country demanded the sacrifice, and that there would be money in it. If the thing is a failure, I want it understood that I was instigated by the Chicago man; but if it is a success, then, of course, it was an inspiration of my own.
