By Elaine Lies TOKYO, Feb 14 (Reuters) - According to author Jim Crace, his latest book will be his last novel. But "Harvest" came about largely by chance, and wouldn't exist at all if a work in progress hadn't failed. Inspired by a painting and a train trip he took in frustration soon after deciding to abandon roughly 100 pages of a novel that just didn't work, "Harvest" is an elegiac look at an English village that has a jarring collision with progress.
