Ending of "Inherit the Wind"

I have to say that this is one of the best books I think we have read in class. I liked all the drama and how we made the class a courtroom. Anyway, to stick on topic, the ending of Inherit the Wind was shocking for me. After Drummond made shut Brady down so hard the previous day, I thought there was no way that Cates would not be let off. The author tricked us, in my opinion. He got us to think that Drummond had the case in his back pocket, and after Brady testified, it seemed so. I liked how he switched everything around and convicted Cates guilty. In addition to the ridiculous verdict, I cannot believe that Brady died at the end! I thought that if Brady had won, there would have been a much bigger celebration. Instead, he is quiet and later dead! The whole book was a page turner, and I am still flabbergasted from the unexpected ending.
