Seraphic Secret follows a pretty rigid daily schedule. I stumble out of bed at 5AM and take a three-mile walk. Usually, I bop along to a music playlist on my iPhone, but for the past few days I’ve been listening to the audio version of Bill O’Reilly’s “Killing Lincoln.” It’s a thrilling book that makes me realize how little I know about central portions of American history. For instance: General Ulysses S. Grant suffered such a severe migraine that he was late for his appointment with General Robert E. Lee at Appamattox Courthouse. Such details make this screenwriter’s heart race with excitement.
