There are a few authors that I looked longingly to their next offering. Louise Penny is one such. Her latest work brings to light again that beloved cast of characters from Three Pines and Quebec. It was delightful to see how she weaved a couple of subplots in and around the main story line. Her use of poetry--Ancient Mariner and Ruth's--added to the mystery. The story had, I felt, more of an intense and frightening nature as one drew nearer to the conclusion. It builds over several chapters and a complete surprise at the end. The concluding revelation of various "cracks" and the title of the book was clever and satisfying. Creatively and pleasingly well done.
