Chatter rolls with Claude, David, Torie, and COB fave Louis Bayard. They revel in the Olympics glow and mourn again Washington Post layoffs, the loss of “Book World” in particular. Poet, teacher, and inspired author Rebecca Lehmann zooms in to share “The Beheading Game.” Few are brave enough to tackle the well-trod ground of Anne Boleyn, the first of Henry the Eighth’s six wives to lose her head. Lehmann does so with imagination, empathy, and provocative thinking. Could not put it down.
