Kate Atkinson writes some complex literary fiction. Her latest novel "Started Early, Took My Dog" derives it's title from a poem by Emily Dickinson. This is her 4th novel featuring private investigator (now retired) Jackson Brodie.
Each book is this series has been utterly different. In the previous one, "When Will There Be Good News?" Brodie spent much of the book in a coma after being involved in a train wreck. He barely existed in that one.
